Harold F. (Hal)Levison (born 1959) is an Americanplanetary scientist specializing in planetary dynamics. He currently works at theSouthwest Research Institute,Boulder, Colorado, and studies planetary orbits and their evolution throughSolar System history.
Levison is the Principal Investigator of theLucy mission to tour multipleJupiter trojans, which was selected as the thirteenth mission in NASA'sDiscovery Program in January 2017.[1]
Among other achievements, Levison is the co-author ofSWIFT, a commonly usedsymplectic integrator that solves planetaryequations of motion for periods ofbillions of years.[2]
Levison argued for a distinction between what are now calleddwarf planets and the other eightplanets based on their inability to "clear the neighborhood around their orbits", although his proposal suggested the terms "unterplanet" and "überplanet" and used the word "dwarf" to mean something else.[3]
