Comet Boethin (or 85P/Boethin) is a periodic comet and the future target of NASA's Deep Impact comet-exploration mission; the plan is to fly the spacecraft by the comet in December of 2008.
The comet was discovered in 1975 by Reverend Leo Boethin. Although the comet was next expected at perihelion on 1997 April 17, no observations were reported.
