* Astronomy

Robert Sutton Harrington (October 21, 1942 - January 23, 1993) was an American astronomer who worked at the United States Naval Observatory (USNO).
Harrington became a believer in the existence of a Planet X beyond Pluto and undertook searches for it, with positive results coming from the IRAD probe in 1983. Harrington collaborated initially with T. C. (Tom) Van Flandern.
The asteroid 3216 Harrington was named in his honour.
