(511002) 2013 MZ5 , provisional designation 2013 MZ5, is a sub-kilometer asteroid, classified as a near-Earth object of the Amor group, estimated to measure approximately 300 meters (1,000 feet) in diameter. It was discovered on 18 June 2013, by astronomers with the Pan-STARRS survey at Haleakala Observatory on the island of Maui, Hawaii, in the United States.[1] It was the 10,000th near-Earth object ever discovered.[4]
Orbit and classification[edit]
2013 MZ5 is an Amor asteroid – a subgroup of near-Earth asteroids that approach the orbit of Earth from beyond, but do not cross it. It orbits the Sun at a distance of 1.3–1.8
Close approaches[edit]
The asteroid has an Earth minimum orbital intersection distance of 69,000,000 km (0.4613
10,000th discovered NEO[edit]
2013 MZ5 was the 10,000th near-Earth object (NEO) ever discovered in June 2013 and considered a significant milestone in exploring the NEO population.[4]
Numbering and naming[edit]
This minor planet was numbered by the Minor Planet Center on 31 January 2018 and received the number 511002 in the minor planet catalog (M.P.C. 108621).[5] As of 2019, it has not been named.[1]
Physical characteristics[edit]
Diameter and albedo[edit]
2013 MZ5 measures approximately 300 meters in diameter for an absolute magnitude of 20.1 and an assumed albedo 0.18, which is typical value for stony asteroids.[3][4] A generic magnitude-to-diameter conversion on a wider range of possible albedos (0.30 to 0.05) gives a diameter between 230 and 570 meters.[3] As of 2019, no rotational lightcurve of 2013 MZ5 has been obtained from photometric observations. The object's effective size, rotation period, pole and shape remain unknown.[2][6]
