Planet
A large body that orbits a star. Planets do not emit light on their
own (but reflect light of their star). A planet may consist of rock
and metals, like the inner planets of Solar System, or or gases and
liqiuds, like the gas giants of Solar System. There is a class of
so called brown dwarf stars in the border area of biggest gas giant
planets and smallest stars that can not clearly be classified as
either.
