Ever wonder how @NASA and other #PlanetaryDefense experts keep track of #NEOs? Through the Minor Planet Center, which is the internationally recognized clearinghouse for the position measurements of small celestial bodies. And, the MPC has a new director: Dr. Matthew Payne!

You may have heard of a behemoth comet barreling its way toward Earth from the edge of the solar system. Don’t worry! It will never get closer than 1 billion miles away from the Sun, which is slightly farther than the distance of the planet Saturn. More: https://go.nasa.gov/37Juse8
