Mainly light and other electromagnetic wave.
Nuclear fusion.
the sun
Fusion.
Mainly electromagnetic radiation.
you give off calary and diet energy
Stars, satellites, and something else
Stars give out light energy, that is they are luminous. Thus we see them for the same reason we see a lighted torch bulb.
Our sun emits mostly visible and ultra-violet radiation
A piano begins with potential energy & converts into kinetic energy!
Firstly, planets are way way smaller than the stars! That's because you can see stars in the night but never planets. Also stars produce nuclear energy in their core so they give thermal ( heat ) energy. Also stars have more gravity than planets.
potential energy
It give off Carbon Dioxide (CO2)
