Everything you need to know about the vagus nerve

The TightSpot quiver's exclusive patent 8,, "RightSpot" 3-way adjustment system lets you fine-tune the balance of your bow using your quiver. TightSpot acts much like a stabilizer, improving the balance of your bow. TightSpot fits tight to your bow and is exceptionally lightweight, which means virtually no torque. Why do so many bowhunters remove their quivers when hunting? Because they shoot better without them!

They are willing to give up having their arrows handy for a second shot to ensure accurate shooting. The problem is the design of most quivers. The further a quiver is from the bow, the more torque it creates. Torque affects accuracy, throws your bow's balance off and makes tuning more difficult, especially with broadheads.

TightSpot's patented dovetail design eliminates this problem! Proximity to the bow is only half the equation. The heavier the quiver, the more torque it exerts. TightSpot quivers win here, too! They're exceptionally lightweight thanks to vibration-absorbing woven carbon rods and a frame machined from aircraft-grade aluminum.

Individually adjustable arrow grippers ensure no more loose or lost arrows. Over time, or in cold weather, arrow grippers on all quivers tend to loosen. No more arrows making noise, vibrating loose or falling out of your quiver!

The TightSpot Quiver's integrated vibration absorption system attacks vibration from every conceivable angle. In fact, these features work so well that your bow will vibrate less with a TightSpot quiver attached than with none at all! Our arrow rests include a combination of innovative features you will not find in any other rest. Each rest is held to precise tolerance specifications and put through strict quality control before leaving our facility.

Nitrogen is completely inert. It is completely non-flamable. Air can fan a fire, but Nitrogen would actually help put-out a fire. Its outer layers will move away into space, leaving a white dwarf , an extraordinarily dense object, half the original mass of the Sun but only the size of Earth. The Sun is the Solar System's star and by far its most massive component. Its large mass , Earth masses , [48] which comprises The Sun is a G2-type main-sequence star.

Hotter main-sequence stars are more luminous. The Sun's temperature is intermediate between that of the hottest stars and that of the coolest stars. The Sun is a population I star ; it has a higher abundance of elements heavier than hydrogen and helium " metals " in astronomical parlance than the older population II stars. The oldest stars contain few metals, whereas stars born later have more. This high metallicity is thought to have been crucial to the Sun's development of a planetary system because the planets form from the accretion of "metals".

The vast majority of the Solar System consists of a near- vacuum known as the interplanetary medium. Along with light , the Sun radiates a continuous stream of charged particles a plasma known as the solar wind. This stream of particles spreads outwards at roughly 1. Earth's magnetic field stops its atmosphere from being stripped away by the solar wind. The interaction of this magnetic field and material with Earth's magnetic field funnels charged particles into Earth's upper atmosphere, where its interactions create aurorae seen near the magnetic poles.

The heliosphere and planetary magnetic fields for those planets that have them partially shield the Solar System from high-energy interstellar particles called cosmic rays. The density of cosmic rays in the interstellar medium and the strength of the Sun's magnetic field change on very long timescales, so the level of cosmic-ray penetration in the Solar System varies, though by how much is unknown.

The interplanetary medium is home to at least two disc-like regions of cosmic dust. The first, the zodiacal dust cloud , lies in the inner Solar System and causes the zodiacal light.

It was likely formed by collisions within the asteroid belt brought on by gravitational interactions with the planets. The inner Solar System is the region comprising the terrestrial planets and the asteroid belt. This region is also within the frost line , which is a little less than 5 AU about million km from the Sun. The four terrestrial or inner planets have dense, rocky compositions, few or no moons , and no ring systems. They are composed largely of refractory minerals, such as the silicates , which form their crusts and mantles , and metals, such as iron and nickel , which form their cores.

Three of the four inner planets Venus, Earth and Mars have atmospheres substantial enough to generate weather ; all have impact craters and tectonic surface features, such as rift valleys and volcanoes.

The term inner planet should not be confused with inferior planet , which designates those planets that are closer to the Sun than Earth is i. Asteroids except for the largest, Ceres, are classified as small Solar System bodies [e] and are composed mainly of refractory rocky and metallic minerals , with some ice. Asteroids smaller than one meter are usually called meteoroids and micrometeoroids grain-sized , depending on different, somewhat arbitrary definitions.

The asteroid belt occupies the orbit between Mars and Jupiter, between 2. It is thought to be remnants from the Solar System's formation that failed to coalesce because of the gravitational interference of Jupiter.

The outer region of the Solar System is home to the giant planets and their large moons. The centaurs and many short-period comets also orbit in this region. Due to their greater distance from the Sun, the solid objects in the outer Solar System contain a higher proportion of volatiles, such as water, ammonia, and methane than those of the inner Solar System because the lower temperatures allow these compounds to remain solid.

For these reasons, some astronomers suggest they belong in their own category, "ice giants". The term superior planet designates planets outside Earth's orbit and thus includes both the outer planets and Mars. The centaurs are icy comet-like bodies whose orbits have semi-major axes greater than Jupiter's 5. Comets are small Solar System bodies, [e] typically only a few kilometres across, composed largely of volatile ices.

They have highly eccentric orbits, generally a perihelion within the orbits of the inner planets and an aphelion far beyond Pluto. When a comet enters the inner Solar System, its proximity to the Sun causes its icy surface to sublimate and ionise , creating a coma: Short-period comets have orbits lasting less than two hundred years.

Long-period comets have orbits lasting thousands of years. Short-period comets are thought to originate in the Kuiper belt, whereas long-period comets, such as Hale—Bopp , are thought to originate in the Oort cloud. Many comet groups, such as the Kreutz Sungrazers , formed from the breakup of a single parent. Beyond the orbit of Neptune lies the area of the " trans-Neptunian region ", with the doughnut-shaped Kuiper belt, home of Pluto and several other dwarf planets, and an overlapping disc of scattered objects, which is tilted toward the plane of the Solar System and reaches much further out than the Kuiper belt.

The entire region is still largely unexplored. It appears to consist overwhelmingly of many thousands of small worlds—the largest having a diameter only a fifth that of Earth and a mass far smaller than that of the Moon—composed mainly of rock and ice. This region is sometimes described as the "third zone of the Solar System", enclosing the inner and the outer Solar System.

The Kuiper belt is a great ring of debris similar to the asteroid belt, but consisting mainly of objects composed primarily of ice. Though it is estimated to contain anything from dozens to thousands of dwarf planets, it is composed mainly of small Solar System bodies. Many of the larger Kuiper belt objects, such as Quaoar , Varuna , and Orcus , may prove to be dwarf planets with further data.

The Kuiper belt can be roughly divided into the " classical " belt and the resonances. The first resonance begins within the orbit of Neptune itself. The classical belt consists of objects having no resonance with Neptune, and extends from roughly The scattered disc, which overlaps the Kuiper belt but extends much further outwards, is thought to be the source of short-period comets. Scattered-disc objects are thought to have been ejected into erratic orbits by the gravitational influence of Neptune's early outward migration.

SDOs' orbits are also highly inclined to the ecliptic plane and are often almost perpendicular to it. Some astronomers consider the scattered disc to be merely another region of the Kuiper belt and describe scattered disc objects as "scattered Kuiper belt objects". The point at which the Solar System ends and interstellar space begins is not precisely defined because its outer boundaries are shaped by two separate forces: The limit of the solar wind's influence is roughly four times Pluto's distance from the Sun; this heliopause , the outer boundary of the heliosphere , is considered the beginning of the interstellar medium.

The outer boundary of the heliosphere, the heliopause , is the point at which the solar wind finally terminates and is the beginning of interstellar space.

The shape and form of the outer edge of the heliosphere is likely affected by the fluid dynamics of interactions with the interstellar medium as well as solar magnetic fields prevailing to the south, e.

Due to a lack of data, conditions in local interstellar space are not known for certain. It is expected that NASA 's Voyager spacecraft , as they pass the heliopause, will transmit valuable data on radiation levels and solar wind to Earth. Mike Brown , who discovered the object in , asserts that it cannot be part of the scattered disc or the Kuiper belt because its perihelion is too distant to have been affected by Neptune's migration.

The second unequivocally detached object, with a perihelion farther than Sedna's at roughly 81 AU, is VP , discovered in Its aphelion is only half that of Sedna's, at — AU. It is thought to be composed of comets that were ejected from the inner Solar System by gravitational interactions with the outer planets.

Oort cloud objects move very slowly, and can be perturbed by infrequent events, such as collisions, the gravitational effects of a passing star, or the galactic tide , the tidal force exerted by the Milky Way. Much of the Solar System is still unknown. The Sun's gravitational field is estimated to dominate the gravitational forces of surrounding stars out to about two light years , AU.

Lower estimates for the radius of the Oort cloud, by contrast, do not place it farther than 50, AU. There are also ongoing studies of the region between Mercury and the Sun. Currently, the furthest known objects, such as Comet West , have aphelia around 70, AU from the Sun, but as the Oort cloud becomes better known, this may change. This revolution is known as the Solar System's galactic year. The Solar System's location in the Milky Way is a factor in the evolutionary history of life on Earth.

Its orbit is close to circular, and orbits near the Sun are at roughly the same speed as that of the spiral arms. Because spiral arms are home to a far larger concentration of supernovae , gravitational instabilities, and radiation that could disrupt the Solar System, this has given Earth long periods of stability for life to evolve.

Near the centre, gravitational tugs from nearby stars could perturb bodies in the Oort cloud and send many comets into the inner Solar System, producing collisions with potentially catastrophic implications for life on Earth. The intense radiation of the galactic centre could also interfere with the development of complex life.

It is thought to be near the neighbouring G-Cloud but it is not known if the Solar System is embedded in the Local Interstellar Cloud, or if it is in the region where the Local Interstellar Cloud and G-Cloud are interacting. The bubble is suffused with high-temperature plasma, that suggests it is the product of several recent supernovae.

There are relatively few stars within ten light-years of the Sun. The closest is the triple star system Alpha Centauri , which is about 4. Alpha Centauri A and B are a closely tied pair of Sun-like stars, whereas the small red dwarf , Proxima Centauri , orbits the pair at a distance of 0. In , a potentially habitable exoplanet was confirmed to be orbiting Proxima Centauri, called Proxima Centauri b , the closest confirmed exoplanet to the Sun.

The largest nearby star is Sirius , a bright main-sequence star roughly 8. The nearest brown dwarfs are the binary Luhman 16 system at 6. Other systems within ten light-years are the binary red-dwarf system Luyten 8.

Compared to other planetary systems the Solar System stands out in lacking planets interior to the orbit of Mercury. Also, these super-Earths have closer orbits than Mercury.

The orbits of Solar System planets are nearly circular. Compared to other systems, they have smaller orbital eccentricity. This section is a sampling of Solar System bodies, selected for size and quality of imagery, and sorted by volume.

Astronomical symbols Ephemeris is a compilation of positions of naturally occurring astronomical objects as well as artificial satellites in the sky at a given time or times. The International Astronomical Union , the authoritative body regarding astronomical nomenclature, specifies capitalizing the names of all individual astronomical objects, but uses mixed "Solar System" and "solar system" in their naming guidelines document.

The name is commonly rendered in lower case " solar system " , as, for example, in the Oxford English Dictionary and Merriam-Webster's 11th Collegiate Dictionary. Although bigger than Mercury, both moons have less than half the mass of Mercury. A planet is any body orbiting the Sun whose mass is sufficient for gravity to have pulled it into a near- spherical shape and that has cleared its immediate neighbourhood of all smaller objects.

By this definition, the Solar System has eight planets: Because it has not cleared its neighbourhood of other Kuiper belt objects, Pluto does not fit this definition. Ceres , Haumea , Makemake , and Eris. Both pairs of coordinates are for J epoch.
