114P/Wiseman–Skiff is a Jupiter-family comet with a 6.67-year orbit around the Sun. It is the only comet discovered by Jennifer Wiseman and one of several by Brian A. Skiff.

Observational history

It was discovered by Jennifer Wiseman in January 1987 on two photographic plates that had been taken on 28 December 1986, by Brian A. Skiff of Lowell Observatory. Wiseman and Skiff confirmed the comet on 19 January 1987.

Aphelion is located near the orbit of Jupiter. On 25 February 2043, the comet will pass 0.179 AU (26.8 million km) from Jupiter.[3]

Physical characteristics

Based on observations conducted by the Hubble Space Telescope, the nucleus of Comet Wiseman–Skiff has a radius of 0.78±0.05 km, assuming a geometric albedo of 0.04.[5]

Meteor shower

Comet 114P/Wiseman–Skiff is believed to have been the parent body of a meteor shower on Mars, and the source of the first meteor photographed from the planet,[7] which was taken by NASA's Spirit rover on 7 March 2004.[8]
