Brown dwarf planetary system

Brown dwarf planetary system

illustration of brown dwarf system is tiny next to solar system

This illustration shows the relative sizes of a hypothetical brown dwarf planetary system compared to our own solar system. Penn State astronmer Kevin Luhman studies how small, cool brown dwarfs are similar to planets and how they are similar to stars, which will provide insight into the process of star and planet formation.
