David Lincoln Rabinowitz (born 1960) is a researcher at
Yale University. He has built
CCD cameras and software for the detection of
near-Earth asteroids and Kuiper Belt Objects, and his research has helped reduce the assumed number of near-Earth asteroids larger than 1 km by half, from 1,000–2,000 to 500–1,000 He has also assisted in the detection of distant solar system objects,
supernovae, and
quasars, thereby helping to understand the origin and evolution of the
solar system and the
dark energy driving the accelerated
expansion of the universe.
