Any natural solar system object other than the Sun, a planet, a dwarf planet, or a moon is called a small body; these include asteroids, meteoroids, and comets. Most of the several hundred thousand asteroids, or minor planets, orbit between Mars and Jupiter in a nearly flat ring called the asteroid belt.

The Solar System [d] is the gravitationally bound system of the Sun and the objects that orbit it. [11] It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc .
Apr 16, 2020 · So worlds made mostly of rock and iron have high density, while those made mostly of ice and rock have low density. Some outer solar system moons, notably Jupiter's Europa and Io, are made mostly of rock and metal, just like the Moon and the terrestrial planets. Most worlds that have lots of ice probably have internal oceans of liquid water.
Size and Distance. Our solar system extends much farther than the planets that orbit the Sun. The solar system also includes the Kuiper Belt that lies past Neptune's orbit. This is a ring of icy bodies, almost all smaller than the most popular Kuiper Belt Object – dwarf planet Pluto. Beyond the fringes of the Kuiper Belt is the Oort Cloud.
The Solar System. The Solar System is the assembly formed by the Sun, eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus & Neptune), their moons and other minor planets. Mercury. Mercury is named for the Greco-Roman messenger of the gods. He was very fast, and Mercury has the shortest and fastest orbit around the sun.
All the foregoing constraints are consistent with the general idea, introduced in Other Worlds: An Introduction to the Solar System, that the solar system formed 4.5 billion years ago out of a rotating cloud of vapor and dust—which we call the solar nebula —with an initial composition similar to that of the Sun today. As the solar nebula collapsed under its own gravity, material fell ...

4 days ago · solar system to scale The eight planets of the solar system and Pluto, in a montage of images scaled to show the approximate sizes of the bodies relative to one another. Outward from the Sun, which is represented to scale by the yellow segment at the extreme left, are the four rocky terrestrial planets (Mercury, Venus, Earth, and Mars), the four hydrogen-rich giant planets (Jupiter, Saturn ...
