(prov. designation: ) is a dark, sub-kilometer near-Earth object and potentially hazardous asteroid of the Aten group that flew by Earth on 6 June 2020. The highly elongated X-type asteroid has a rotation period of 14.5 hours and measures approximately in diameter. It was discovered by LINEAR at the Lincoln Laboratory's Experimental Test Site in New Mexico on 9 July 2002.
' flew by Earth on 6 June 2020, passing from Earth. The asteroid had been recovered two days earlier on 4 June 2020. By 11 June 2020, the asteroid had brightened to apparent magnitude 14.4, which is roughly the brightness of Pluto.
Being a member of the Aten asteroids, ' orbits the Sun at a distance of 0.50âÂÂ1.26 AU once every 10 months (300 days; semi-major axis of 0.88 AU). Its orbit has an eccentricity of 0.43 and an inclination of 5ð with respect to the ecliptic. It was first observed by the Near-Earth Asteroid Tracking on Palomar Observatory on 2 July 2002, or seven nights prior to its official discovery observation by LINEAR. This asteroid has an Earth minimum orbit intersection distance of , which corresponds to 2.7 lunar distances (LD).
A spectroscopic survey of the small near-Earth asteroid population conducted by European astronomers determined that ' is an X-type asteroid. Because of the objects low albedo (see below), it would be considered a primitive P-type asteroid in the Tholen classification.
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, ' measures () meters in diameter, and its surface has a dark albedo of (). (The NEOWISE publication uses the designation G3348 for this asteroid.) In 2016, astronomers using the European New Technology Telescope at La Silla Observatory found a diameter of 613 meters with an albedo of 0.047.
In August 2016, the first rotational lightcurve of ' was obtained from photometric observations over five nights by Brian Warner at the Center for Solar System Studies in California. Lightcurve analysis gave a rotation period of hours with a high brightness variation of magnitude, indicative of a highly elongated shape ().
