    All stars are fusion reactors converting hydrogen to helium and heavier elements. As a consequence heat is given off and they are hot. Planets are rocky, icy or gaseous bodies orbiting stars and have little or no internal heat and are thus cold apart from warmth they pick up from their star.

    Yes, all stars are hot.

    Some are small, almost the size of Jupiter. But they are all hot.

    Stars are a balance between explosive force and gravity , at the end of a stars life, depending on the size density, etc it will either go supernova and explode or collapse into a black hole.their is no inbetween. So no, their is no such thing as a cold atar

    Your choice for best answer is correct. One other thing Stars (all of them) are Suns.

    No difference between a Star and a Sun. A Gas Giant undergoing Nuclear Fusion.

    White dwarf stars and neutron stars can in principle be cold, although the time for them to cool off is longer than the age of the Universe, so none actually are cold.

    There's a continuum from very big planets to very small stars ("brown dwarfs"). Although very big planets are warm because they are still getting energy from gravitational contraction.
