Stars are much bigger than planets, and thus are hot and dense enough at the core to support nuclear fusion, which creates the light and heat and radiation we get from them. Planets don't create their own light, and very little of their own radiation, so they mostly reflect starlight. The light we see from Jupiter is reflected sunlight.

Everything we see is a result of light rays reflecting off of a surface. The nuclear fission taking place in a star like our Sun generates the light source and heat energy.
In the material of your clothes, we see ridges in fabric as light hitting the grooves is being reflected away from your eyes which makes the grooves appear to be darker than the surfaces. This same effect occurs with light reflecting off of the surface of planets.

Stars shine because they generate light thru nuclear fusion in their core. Planets shine because they reflect light that comes from stars.

Reflective light. Light from stars hits planets and you see the light reflected off.

Stars are like giant balls of superhot fire which creates light that reflects from the surface of planets. Planets don't shine, stars do.

Light.
If you're asking for where the light comes from, it comes from the sun for planets. Stars are so hot that they make light themselves. They would be described as "incandescent". Lightbulbs are based on the same principle.
