John Asher Johnson is an American astrophysicist and professor of astronomy at Harvard. He was a formerly a professor at the California Institute of Technology and a researcher with NASA's Exoplanet Science Research Institute.
In 2012 Johnson's team discovered three exoplanets, including the smallest one found to date, orbiting a red dwarf using the Kepler orbital telescope.[1] A subsequent study used the host star's similarity to Barnard's star and observations from the Keck Observatory to determine more information about the system and the size of its three planets.[2] He is the principal investigator of the Miniature Exoplanet Radial Velocity Array (MINERVA), a ground-based robotic search for exoplanets.[3]
