      Stars, Planets and Brown Dwarfs are very different from each other.

Planets

      Planets form from small particles of dust. Their tempereture isn’t enough to release energy. So they shine by reflecting light.

 

Stars

      Stars form from a cloud of gas that contracts, triggering nuclear reactions that produce  heat and light. So they shine by producing light.

 

Brown Dwarfs

      Brown Dwarfs aren’t Planets neither Stars. They form from gases like a star, but the nuclear reactions don’t initiate because Brown Dwarfs don’t have enough mass. So they are cold and don’t produce much light.
