(385343) 2002 LV, provisional designation 2002 LV, is a stony asteroid on a highly eccentric orbit, classified as near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 1.5 kilometers (0.9 miles) in diameter. It was discovered on 1 June 2002, by astronomers with the Lincoln Near-Earth Asteroid Research at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico, in the United States.^[1] The Sr-type asteroid has a rotation period of 6.2 hours and is likely elongated.^[4]

Orbit and classification[]

2002 LV is a member of the Earth-crossing group of Apollo asteroids, the largest group of near-Earth objects with approximately 10 thousand known members.^[1]^[2]

It orbits the Sun at a distance of 0.9–3.7 AU once every 3 years and 6 months (1,286 days; semi-major axis of 2.31 AU). Its orbit has an eccentricity of 0.61 and an inclination of 30° with respect to the ecliptic.^[2] Due to its large aphelion, it also crosses the orbit of Mars at 1.66 AU.^[2] The body's observation arc begins with its official discovery observation at Socorro in June 2002.^[1]

Close approaches[]

The asteroid has an Earth minimum orbital intersection distance of 0.0071 AU (1,060,000 km; 660,000 mi), which corresponds to 2.7 lunar distances and makes it a potentially hazardous asteroid due to its notably large size.^[2] In August 1935, it approached Earth at a nominal distance of 0.035 AU (14 LD), and in July 2002 at 0.112 AU (44 LD). Its closest near-Earth encounter is predicted to occur on 4 August 2076 at a distance of 0.0108 AU (4.2 LD) only (see table).^[9]

Physical characteristics[]

Observations with the Spitzer Telescope characterized this object as an Sr-subtype that transitions from the common, stony S-type asteroids to the uncommon R-types.^[8]

Rotation period[]

In July 2002, a rotational lightcurve of this asteroid was obtained from photometric observations by Petr Pravec at Ondřejov Observatory in the Czech Republic. Lightcurve analysis gave a well-defined rotation period of 6.195 hours with a high brightness amplitude of 0.93 magnitude, indicative for an elongated, non-spherical shape (U=3).^[a] The result agrees with a period of 6.2 hours measured at the Table Mountain Observatory and at the CS3-Palmer Divide Station (U82) in 2009 and 2016, respectively (U=2+/3-).^[6]^[7]

Diameter and albedo[]

According to post-cryogenic observations with the Spitzer Telescope during the ExploreNEOs survey, and observations carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, this asteroid measures between 1.359 and 1.73 kilometers in diameter and its surface has an albedo between 0.15 and 0.2158.^[3]^[5] The Collaborative Asteroid Lightcurve Link assumes a stony standard albedo of 0.20 and calculates a diameter of 1.42 kilometers based on an absolute magnitude of 16.6.^[4]

Numbering and naming[]

This minor planet was numbered by the Minor Planet Center on 14 February 2014 (M.P.C. 87072).^[10] As of 2018, it has not been named.^[1]
