Twenty years ago, today, on 17 February 1996, NASA’s Near-Earth Asteroid Rendezvous (NEAR)—a name later adjusted to honor the planetary scientist Gene Shoemaker—rocketed away from Launch Complex (LC)-17B at Cape Canaveral Air Force Station, Fla., aboard a venerable Delta […]

Is 'Planet 9' Really a Second Massive Kuiper Belt?

The Kupier Belt is a massive collection of dwarf planet and asteroid-sized worlds orbiting far past Neptune. Is the hypothetical Planet 9 really a second such belt? Image Credit: T. Pyle (SSC)/JPL-Caltech/NASA
