Our solar system consists of our star, the Sun, and everything bound to it by gravity — the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, dwarf planets such as Pluto, dozens of moons and millions of asteroids, comets and meteoroids.

According to our theory of solar system formation, why do we find some exceptions to the general rules and patterns of the planets? Most of the exceptions are the result of giant impacts or close gravitational encounters.

A “planet” [1] is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.

Large bodies in the solar system have orderly motions. All planets and most satellites have elliptical, often nearly circular, orbits in nearly the same plane and revolve in the same sense (counterclockwise when looking down on the North Pole).

The gas and ice giants — Jupiter, Saturn, Uranus and Neptune — are outliers. They are much larger than the terrestrial planets, but their cores are small and icy. Most of their size is formed by a combination of gases that become denser and hotter as you get closer to the core. Scientists count eight planets overall.

The Solar System is made up of all the planets that orbit our Sun. In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, dust and gas. The inner solar system contains the Sun, Mercury, Venus, Earth and Mars. The main asteroid belt lies between the orbits of Mars and Jupiter.

What is another word for solar system?

polar energy. it is the polar opposite of solar energy. the sun is the source of energy, light and heat that living things need to survive. polar energy can be thought of as the absence of solar energy.

However, the planets can be divided into two main groups: rocky planets, (Mercury, Venus, Earth, and Mars) which are also called terrestrial planets and have very rocky surfaces; and gas planets -also called gas giants- are, like the name says, made of different gases, and these are Jupiter, Saturn, Uranus, and Neptune …
