(467336) 2002 LT38, is a sub-kilometer asteroid and suspected tumbler, classified as a near-Earth object and potentially hazardous asteroid of the Aten group, approximately 240 meters (790 ft) in diameter. It was discovered on 12 June 2002, by astronomers of the Lincoln Near-Earth Asteroid Research at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico, in the United States. [2]
2002 LT38 orbits the Sun at a distance of 0.6–1.1 AU once every 9 months (284 days; semi-major axis of 0.85 AU). Its orbit has an eccentricity of 0.31 and an inclination of 6 ° with respect to the ecliptic. [1]
The body's observation arc begins with a precovery taken at AMOS on 10 June 2002, two nights prior to its official discovery observation at Lincoln Lab's ETS. [2]
2002 LT38 has an Earth minimum orbital intersection distance of 0.0344 AU (5,150,000 km) which corresponds to 13.4 lunar distances. [1] It will pass at that distance during its close encounter with Earth on 27 June 2030. [1]

The asteroid is an assumed stony S-type asteroid. [3]
In July 2016, a first rotational lightcurve of 2002 LT38 was obtained from photometric observations by American astronomer Brian Warner at his Palmer Divide Station in California ( U82). Lightcurve analysis gave a longer-than average rotation period of 21.80 hours with a brightness variation of 1.16 magnitude ( U=2+). [5] [a] A high brightness amplitude typically indicates that the body has a non-spherical, elongated shape. It is also a suspected tumbler. [5]
The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 0.236 kilometers based on an absolute magnitude of 20.5. [3]
This minor planet was numbered by the Minor Planet Center on 21 May 2016, after its orbit determination became sufficiently secure ( M.P.C. 100286). [8] As of 2018, it has not been named. [2]
