Spacewatch was founded in 1980 by Tom Gehrels and Robert S. McMillan, and is currently led by astronomer Melissa Brucker at the University of Arizona. Spacewatch uses several telescopes on Kitt Peak for follow-up observations of near-Earth objects. [3] The Spacewatch Project uses three telescopes of apertures 0.9-m, 1.8-m, and 2.3-m.
125P/Spacewatch is a periodic Jupiter-family comet. It was discovered on September 8, 1991, by Tom Gehrels using the 0.91 m Spacewatch telescope at the Kitt Peak National Observatory . [ 4 ] It was the first comet discovered with the use of a CCD [ 5 ] and also the faintest comet upon discovery up to that point. [ 4 ]
It was discovered on 8 April 2008, by astronomers of the Spacewatch program at Kitt Peak National Observatory near Tucson, Arizona, in the United States. [1] This presumably carbonaceous body has a diameter of approximately 15 kilometers (9 miles) and rotation period of 10.7 hours.
Periodic comets (also known as short-period comets) are comets with orbital periods of less than 200 years or that have been observed during more than a single perihelion passage [1] (e.g. 153P/Ikeya–Zhang).
