2044 Wirt, provisional designation 1950 VE, is a

Mars-crosser, approximately 6.7 kilometers in diameter. The minor-planet moon
has an estimated diameter of 1.89 kilometer.

The asteroid was discovered on 8 November 1950, by American astronomer

Carl Wirtanen at Lick Observatory on Mount Hamilton, California, and later named after the discoverer himself.[3]

Orbit and classification

Wirt is both a member of the main-belt's

Mars-crossing asteroid, whose orbit crosses that of Mars.[1][3][4][5] It orbits the Sun in the inner main-belt at a distance of 1.6–3.2 AU once every 3 years and 8 months (1,342 days). Its orbit has an eccentricity of 0.34 and an inclination of 24° with respect to the ecliptic.[1]

The asteroid's observation arc begins two weeks after its official discovery with the first recorded observation at Lick Observatory on 22 November 1950.[3]

Physical characteristics

Wirt has been characterized as a stony S-type asteroid.[4]

Rotation period

Between 2005 and 2010, several rotational

U=n.a./3/3/3/3/2).[6][7][9][10][11]

Satellite

During the photometric observations in December 2005, a minor-planet moon in orbit of Wirt was discovered. The binary asteroid has diameter ratio of 0.25, and the moon's orbital period is 18.97 hours. It measures approximately 1.89 kilometer in diameter.[6][7][10]

Diameter and albedo

According to the survey carried out by the Infrared Astronomical Satellite

albedo of 0.19,[8] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.23 and calculates a diameter of 6.65 kilometers with an absolute magnitude of 13.1.[4]

Naming

It was named after American astronomer

M.P.C. 5688).[12]
