Kevin Luhman

Kevin Luhman is a professor of astronomy and astrophysics from Pennsylvania State University who discovered both the third-closest stellar system, Luhman 16, and the fourth-closest stellar system, WISE 0855−0714, to the Sun. Both systems are composed of substellar objects, falling into the category of brown dwarfs or even less massive objects which are categorized as sub-brown dwarfs but also referred to as "free floating planets" or "planetary mass objects". WISE 0855−0714 is the coldest massive object outside the Solar System that has been directly imaged.
