Question

what is planets Related:  Solar System vs Galaxy vs Universe?

Answer

A planet is a large object such as Jupiter or Earth that orbits a star. Planets are smaller than stars, and they do not produce light. ... Planets are shaped like a slightly squashed ball (called a spheroid). Objects that orbit planets are called satellites.

Answer

A planet 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.

Answer

The planets are the heavily and celestial bodies that move on a fixed path called orbit. The planets are too much smaller than stars They receive light and heat from sun. They do not have their own light. The total number of planets in solar system are eight. In order of their distance from sun, they are Mercury , Venus , Earth , Mars , Jupiter , Saturn, Uranus , Neptune . The first four planets in order of their distance from sun are - Mercury , Venus , Earth , Mars. They are called as terrestrial planets because they have solid rock surface. Two of the outer planets , Jupiter and Saturn are known as gas giants whereas the more distant , Uranus and Neptune are called ice giants.
Mercury has a thin atmosphere.The days are hot but night temperature drops hundreds of degree below freezing point. It is the smallest planet in the solar system. Venus is the hottest planet due to its volcanic activities and thick atmosphere. It spines backward. Earth our home planet is only planet which supports life due to its optimum amount of heat, light and oxygen. Mars known as the red planet , is a cold desert . Its atmosphere is too thin for liquid water to exist for long on the surface. Jupiter Saturn Uranus and Neptune have rings. The rings around Jupiter are very faint hence, can't be seen with naked eyes. The atmosphere of Jupiter Saturn Uranus is mostly made of hydrogen and helium. other than these Uranus has methane , which gives blue tint to it. Neptune is similar in composition to Uranus composed primarily of hydrogen and helium along with traces of hydrocarbons and nitrogen.
