* The Sun is the source of light and heat for the solar system. This means that all the planets in our system receive sunlight, but the amount of light they receive varies greatly.
* Distance matters. Planets farther away from the Sun get much less light than those closer to it. For example, Pluto, the farthest planet, receives a tiny fraction of the sunlight that Earth does.
* Orbiting the Sun. The planets all orbit the Sun at different distances and speeds, so the amount of sunlight they receive changes throughout their orbits.
So, while the Sun does provide light for all the planets, it's not evenly distributed.
