Question

hi friends I have a ouestion but please no spamming the answer why stars emit light?and why don't planet emit visible light?

Answer 1

there are different in showing light...
there are 2 categories for this..
1: Luminous objects- those who emit there lights own....
2:Non-luminous objects- those who are reflecting light ...they do not have their own light....
in case of ur question. some planets have their own light like Sun but not all planet can emit light...they reflect light from a Luminous object
planet don't emit ligh bkz they do not have any source to produce light...stars are like a burning planet..like sun so they emit light
i hope u understand
