Like our photo? my question:

Why does the sun give heat?

NO LINKS OR I REPORT​

Because it's a ball of fire and plasma that's extremely hot, Therefore it gives off heat.

Also your pfp is gross...? You should change it before your acc goes down-

And no, I don't like the image.

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !
