Nuclear Fusion and Fission from the Suns' core.
No, planets don't give off light, stars did.
First of all, planets are way smaller than stars, stars are probably 10-1000's of times bigger than plants. Another thing is stars produce nuclear energy in their core so they burn and give of heat, which by far planets don't give off. The third thing is Stars have more gravity than planets so they make smaller bodies orbit around them. Planets are dark balls of rock and gas that orbit a star and stars are giant balls of hot gases that makes its own light and heat
Because at night it functions as a mirror for the sun. It's like this: You -------> (watch in this direction) ----> Moon (mirroring the sunlight in your eye) -------------------------------------- ..................^ Earth (blocks the sun) ............................../ .............................................................../ ............................................................/ ........................................................./ ....................................................../ ..................................................Sun (forget about the dots, that's just to position the lines because I can't type spaces in this drawing)
The sun is the primary source of external heat for all eight planets, although in the case of some planets it doesn't provide a lot of heat. The sun also is the largest single factor affecting the orbits of the eight planets.
Light and heat are the same stuff; electromagnetic energy. The difference is in the wavelength of the energy; heat has longer wavelengths than light. (It's all one broad spectrum from radio to heat to light to x-rays to gamma rays to cosmic rays; all electromagnetic energy.

sun
yes, as the light travels it brings along heat to all of the planets.
Planets dont give off light therefore all planets dont give off its own light
Yes. The sun produces all the heat and light energy to all the planets in the Solar System.
Because, if it wasn't for heat, there would be no light at all. The sun is blazing hot and gives off light. Our light bulbs require heat to produce light. Many other things.
The sun. All other objects reflect heat and light from the sun.
All objects warm enough to glow. It depends on what you count as 'light'. If you count all electromagnetic radiation, then all objects above absolute zero give off their own heat and light. Except, maybe, black holes. The answer for them is not so clear-cut.
No, planets don't give off light, stars did.
Fireflies are remarkable in that they produce light without also producing heat. All of their energy resources are used very efficiently to make light energy without wasting heat energy.
