NASA/JPL-Caltech

Welcome to Scratching the Surface with Caitlin Ahrens, the Pluto Manager at the University of Arkansas Center for Space and Planetary Science. 

What is a planet without a place to call home? Well, according to the International Astronomical Union- infamous for demoting Pluto- they are called sub-brown dwarfs officially. Don't let the name fool you, though, most of these "dwarfs" are about the size of Jupiter. 

In this episode we learn about some of the exceptional, oddball "planets" that find themselves outside of the solar system. 

Scratching the Surface airs Fridays at 2:04 pm. For more on the Center for Space and Planetary Science, visit spacecenter.uark.edu/
