The Sol System - Resource

The Sol System is the system of origin of the Terrans. (from the third planet of that system called Earth (Terra)).It consists of a sun called Sol and astronomical objects gravitationally bound in orbit around it, all of which formed from the collapse of a giant molecular cloud approximately 4.6 billion years ago. The vast majority of the system's mass (well over 99%) is in its sun. Of the many objects that orbit Sol, most of the mass is contained within eight relatively solitary planets[e] whose orbits are almost circular and lie within a nearly flat disc called the ecliptic plane. The four smaller inner planets, Mercury, Venus, Earth and Mars, also called the terrestrial planets, are primarily composed of rock and metal. The four outer planets, the gas giants, are substantially more massive than the terrestrials. The two largest, Jupiter and Saturn, are composed mainly of hydrogen and helium; the two outermost planets, Uranus and Neptune, are composed largely of ices, such as water, ammonia and methane, and are often referred to separately as "ice giants". The Sol System is also home to a number of regions populated by smaller objects. The asteroid belt, which lies between Mars and Jupiter, is similar to the terrestrial planets as it is composed mainly of rock and metal. Beyond Neptune's orbit lie the Kuiper belt and scattered disc; linked populations of trans-Neptunian objects composed mostly of ices such as water, ammonia and methane. Within these populations, five individual objects, Ceres, Pluto, Haumea, Makemake and Eris, are recognized to be large enough to have been rounded by their own gravity, and are thus termed dwarf planets. In addition to thousands of small bodies in those two regions, various other small body populations, such as comets, centaurs and interplanetary dust, freely travel between regions. Six of the planets and three of the dwarf planets are orbited by natural satellites, usually termed "moons" after Earth's Moon. Each of the outer planets is encircled by planetary rings of dust and other particles. The solar wind, a flow of plasma from the sun, creates a bubble in the interstellar medium known as the heliosphere, which extends out to the edge of the scattered disc. The Oort cloud, which acts as the source for long-period comets, exist at a distance roughly a thousand times further than the heliosphere. The Solar System is located in the Milky Way galaxy, which contains about 200 billion stars.

The largest of these may lie above the boundary for hydrostatic equilibrium, but most are irregular. Most of the trans-Neptunian objects listed with a radius smaller than 200 km have "assumed sizes based on a generic albedo of 0.09" since they are too far away, with existing instruments, to directly measure their sizes. Values relative to Earth are not included beyond this point. Mass switches from 1021 kg to 1018 kg (Zg), with Mimas double listed as example of unit shift. Main-belt asteroids have orbital elements constrained by (2.0 AU < a < 3.2 AU; q > 1.666 AU) according to JPL Solar System Dynamics (JPLSSD).[33] This is not complete, missing many poorly known TNOs.[34] Satellites of Jupiter Satellites of Saturn Satellites of Uranus Satellites of Neptune Body Image Mean radius (km) Mass ×1018 kg (Zg) Type of object Shape Mimas‡ Saturn I

1[3] 0.015 Satellite of Jupiter [edit] Examples of objects below 1 km (1000 m) in radius In the asteroid belt alone there are estimated to be between 1.1 and 1.9 million objects with a radius above 0.5 km,[128] many of which are in the range 0.5–1.0 km. Countless more have a radius below 0.5 km. Very few objects in this size range have been explored or even imaged. The exceptions are objects that have been visited by a probe, or have passed close enough to Earth to be viewed by large telescopes. Radius is by mean geometric radius. Number of digits not an endorsement of significant figures. Mass scale shifts from × 1015 to 1012 kg, which is 1015 grams (Petagram - Pg).
