a light-year is the speed at which light travels from the sun to earth.
planets sometimes look brighter than stars because of reflected light from the sun.

I think the correct statement is "Planets sometimes look brighter than stars because of reflected light from the sun." The stars make their own light but planets don't. The light we see is due to their reflection of the light from the sun which is also the case for our moon lighting up during the night.
