Stars are massive balls of gas with pressure inside them that causes a nuclear reaction, which makes them bright and hot. A object would have to have 80 times the mass of Jupiter to have the nuclear reaction in its core. Making planet's not big enough to be a star. Although there is a huge difference in size and mass, many stars and planets are similar. Many planets are rocky and metallic like Earth and Mars, but some planets are mostly made up of gas, like a star. Both gas planets and stars are largely made up of hydrogen and helium. Atoms of hydrogen are being fused into atoms of helium at the
