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.
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.

A chart datum is the water level surface serving as origin of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. [1] Common chart datums are lowest astronomical tide (LAT) [1] and mean lower low water (MLLW).
[1] [3] [4] If available, mean diameters are taken from the latest NEOWISE publication, [5] or, if not available, estimated based on an object's absolute magnitude and displayed in italics. [ 6 ] In the Minor Planet Circular from July 2018, the MPC announced that changes in their data processing pipeline will enable numberings to occur more ...
1991 VG is a very small near-Earth object of the Apollo group, approximately 5–12 meters (16–39 feet) in diameter.It was first observed by American astronomer James Scotti on 6 November 1991, using the Spacewatch telescope on Kitt Peak National Observatory near Tucson, Arizona, in the United States.

1998 KY 26 orbits the Sun at a distance of 1.0–1.5 AU once every 16 months (500 days). Its orbit has an eccentricity of 0.20 and an inclination of 1 ° with respect to the ecliptic . It has an Earth minimum orbital intersection distance of approximately 0.0025 AU (374,000 km; 232,000 mi), corresponding to 0.98 lunar distances .
