Orbital Plane

Apr 4, 2024· All the planets, asteroids, meteoroids, and comets in the solar system orbit the sun.This is called heliocentric orbit. Almost all these bodies also travel in the same orbital plane, a thin disk surrounding the sun and extending to the edge of the solar system.The orbital plane usually prevents planets or other celestial bodies from bumping into each other.

What type of star orbits the Sun?

Astronomers classify it as a G-type main-sequence star. The largest objects that orbit the Sun are the eight planets. In order from the Sun, they are four terrestrial planets (Mercury, Venus, Earth and Mars); two gas giants (Jupiter and Saturn); and two ice giants (Uranus and Neptune). All terrestrial planets have solid surfaces.

The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc. The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its outer photosphere. Astronomers
