the sun.

Because black absorbs all light whereas white reflects all light back. The energy that black absorbs as light manifests itself as heat.
The gravitational pull between the planets and the sun keep the planets orbiting the sun all day everyday.
Some ignition source is required. Like explosives, some spark or explosion is needed to start the chain reaction. Otherwise it will sit there and not do anything.
No Infact. The World Will End Completely In Millions and billions of years because the sun will burn out and When the sun burns out All the planets will become cold with no heat and kill us off FAST, and it is very unlikley that another star will get in the same spot as our star ( aka: Sun ) and it will be to cold to have life like ( the asteroid Pluto ) and our Sun Will never heat the earth and others again.

The Sun is the primary source of heat and light for all the planets in our solar system. It emits energy through nuclear fusion reactions in its core, which produces heat and light that reach all the planets, including Earth.
Heat for all the planets and the main reason for the orbits of the planets.
The sun is the source of heat and light for plant-life.
yes, as the light travels it brings along heat to all of the planets.
the sun.
The source of light in outer space varies. Light can be reflected off from the stars, moons, comets, asteroids and planets.
Yes. The sun produces all the heat and light energy to all the planets in the Solar System.
Yes. and No. It all depends on the heat given off the source of the artificial light.
Stars (of which our sun is one) are the only sources of light in space. Planets, moons, asteroids, comets, etc. all simply reflect starlight.
