KNOXVILLE—Astronomy enthusiasts and the space science community recently have been abuzz with the theory of Planet Nine, a space body 10 times bigger than the earth orbiting the sun and tucked not far from Neptune.

The potential planet would be part of the Kuiper Belt objects—icy bodies that orbit the sun beyond Neptune. Pluto is one of the largest Kuiper Belt objects.

NASA cautions that the existence of the planet is a theory, not an actual discovery.

Josh Emery, assistant professor of earth and planetary sciences at the University of Tennessee, Knoxville, is available to discuss the Planet Nine theory and what it could mean for the scientific community.

He's spent the past 10 years analyzing telescopic data from Kuiper Belt objects and the surface composition of icy dwarf planets. He is an expert in astronomy, particularly that of our own solar system.
