Question

write short note - Astereids, earth, satellites
​

Answer 1

Answer:

An asteroid is a minor planet of the inner Solar System. Historically, these terms have been applied to any astronomical object orbiting the Sun that did not resolve into a disc in a telescope and was not observed to have characteristics of an active comet such as a tail. As minor planets in the outer Solar System were discovered that were found to have volatile-rich surfaces similar to comets, these came to be distinguished from the objects found in the main asteroid belt.[1] The term "asteroid" refers to the minor planets of the inner Solar System, including those co-orbital with Jupiter. Larger asteroids are often called planetoids.

The earth is the third planet to the sun. In size, it is the fifth-largest planet. It is slightly deflated at the poles. The Earth shape is described as a Geoid.

A satellite is an object that orbits another object. In space, satellites may be natural, or made by man. The moon is a natural satellite that orbits the Earth. Most man-made satellites also orbit the Earth, but some orbit other planets, or the Sun or Moon.
