What is the difference between a planet and a star?

• Answer:

  Difference Between a Planet and a Star A star contains much more mass than a planet, enough that gravitational forces have compressed the matter enough to start a fusion reaction at the nuclear level, radiating the resultant energy out. A planet orbits a star in a regular manner. The sum of a star and it's orbiting planets is called a Solar System. Stars are always much bigger than planets. Also, their content is different. stars are made of mostly hydrogen, which they push together to form helium. this is then pushed together to form other elements which are blown into space. (although one star nicknamed Lucy has got alot of carbon in its core, which because of the pressure has formed a diamond which is a billion billion carats.) planets are different. although they may be made of gas, like Jupiter, they are different gases to the ones in stars. also, it is actually very unlikely that it is made from gases. it is usually molten iron and rock. A star is a burning mass of (mainly) hydrogen and helium. The outer planets are also made out of hydrogen and helium. Neptune and Uranus theirs also have methane,hydrogen, and helium in it that's why both planets are blue. A planet is a body which moves in an orbit around a star. A planet (of any sort, dwarf or other) is defined as "any celestial body which orbits a star." The earth is a planet. A star is typically a big, burning, ball of gas around which planets tend to orbit. (except when it goes out, then it is a black hole or a neutron star.) The sun is a star. Fun fact: The only place gold comes from is supernovas. All gold is made in supernovas.
