What is the name given to an object which gives out its own light?

Answer 1

As matter becomes excited(heated) it releases photons of light. Stars do this very well through nuclear fusion. These photons are observed by us on earth.

The moon, and other planets in our solar system are close enough that they are observable via light that is reflected off of them from our own sun.

Most other planets in distant solar systems are only recently observed by observing a distance star's very subtle movement as the mass of it's orbiting planets pulls on it, much like our planet experiencing tidal flows in our oceans caused by our moon.

These very distant planets are mostly invisible to us, unless they happen to eclipse a star.

Answer 2

I'm not real sure but I THINK that the objects in the solar system such as "the earth's moon" gives off light reflected from the sun to the moon,same thing goes for other objects and planets....i study outer space a lot so i know this stuff very well :D

Answer 3

Generally speaking, the word "luminous" means something gives off its own light. Our sun and the stars are luminous. Planets and moons are not; they simply reflect a certain percentage of the light that falls on them from the sun or whatever star they're orbiting.
