“(50719) 2000 EG140”的意思、由来-开放百科全书

The stony S-type asteroid is a member of the Eunomia family, the most prominent family in the intermediate main-belt. It orbits the Sun at a distance of 2.2–2.9 AU once every 4 years and 2 months (1,518 days). Its orbit has an eccentricity of 0.13 and an inclination of 14° with respect to the ecliptic. A first precovery was taken at Lowell Observatory (LONEOS) in 1998, extending the asteroid's observation arc by 2 years prior to its discovery.^[17]

Physical characteristics

Slow rotator

In August 2010, a rotational lightcurve was obtained for this asteroid from photometric observations at the U.S. Palomar Transient Factory (PTF) in California. It gave a rotation period of 1256 hours with a brightness variation of 0.42 magnitude ({{small|U=2}}).^[7] This makes the asteroid the 5th slowest rotating minor planet known to exist.

Diameter and albedo

According to the surveys carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 3.3 kilometers in diameter and its surface has an albedo of 0.37,^[4]^[5] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.21 and calculates a diameter of 3.4 kilometers with an absolute magnitude of 14.65.^[2]

Numbering and naming

This minor planet was numbered by the Minor Planet Center on 20 November 2002.^[24] As of 2018, it has not been named.^[17]
