Spacewatch conducted a survey that was proposed May 12, 2006, and accepted on November 13, 2006. This survey used data taken over 34 months by the University of Arizona’s Spacewatch Project based at Steward Observatory, Kitt Peak. Spacewatch revisited the same sky area every three to seven nights in order to track cohorts of main-belt asteroids.
The following is a partial list of minor planets, running from minor-planet number 757001 through 758000, inclusive.The primary data for this and other partial lists is based on JPL's "Small-Body Orbital Elements" [1] and data available from the Minor Planet Center.
The following is a partial list of minor planets, running from minor-planet number 742001 through 743000, inclusive.The primary data for this and other partial lists is based on JPL's "Small-Body Orbital Elements" [1] and data available from the Minor Planet Center.
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 ]
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).
2006 VW 139 is a non-family asteroid of the main-belt's background population. [9] It is both a binary asteroid and a main-belt comet, also known as "active asteroid".It orbits the Sun in the outer main-belt at a distance of 2.4–3.7 AU once every 5 years and 4 months (1,944 days; semi-major axis of 3.05 AU).
The Collaborative Asteroid Lightcurve Link assumes a standard albedo for a carbonaceous body of 0.057 and calculates a diameter of 14.64 kilometers based on an absolute magnitude of 12.9. [4] Other estimates, taking into account several published magnitude measurements and a large range of albedo assumptions, estimate a diameter range of 5.5 to ...
The LINEAR and Spacewatch (Kitt Peak, Arizona) surveys continued observing Dinkinesh until 15 November 1999, after which the asteroid became lost and went unrecognized for years. [ 2 ] On 19 April 2004, Spacewatch reobserved Dinkinesh as a seemingly new asteroid, but misattributed these observations to those of another unrelated asteroid, 2004 ...
