Group 1 Luminous Objects
a luminous object is a object that gives out light, some poeple get confused about which objects give out light because some reflect light, but lookn like they are giving light out. e.g. the moon. The sun is a luminous object because it gives out light, without the sun there would be no light!
All stars are luminous objects because they are all suns, in fact are sun is smaller than most other stars/suns
Stars shine because they are hot. They're hot because there fusing hydrogen atoms together to make helium, which gives off loads of energy.
