Stars, planets, moons, and asteroids are four types of celestial bodies found in space. Stars are massive luminous spheres of plasma, planets are large bodies orbiting around stars, moons are natural satellites orbiting planets, and asteroids are small rocky bodies that orbit the Sun.
Astronomer
Our Sun belongs to the category of stars known as main sequence stars, specifically a G-type main sequence star. It is classified as a yellow dwarf star.
The stellar classification of Class K stars are orange and are slightly cooler than our Sun.Notable K type stars are Arcturus which is a supergiant and Alpha Centauri B which is an orange dwarf.K type stars will have a slightly longer period on the main sequence than our own Sun, which is a G type star, and thus K type stars are a good candidate for possible planets and life.See related link for more information.
Currently, this type of scientist does not exist, since no current technology can keep a man alive for a mission further than the Moon.
None Stars are gas Planets are solid
Isaac Newton -- invented calculus and a type of telescope that was more compact, but gave better magnification to see planets, stars, etc.
