6170 Levasseur, provisional designation 1981 GP, is a stony Phocaean

rotation period of 2.65 hours.[3] It was named for French planetary scientist Anny-Chantal Levasseur-Regourd.[1]

Orbit and classification

Levasseur is a member of the

HCM algorithms to its proper orbital elements.[4][8]
: 23 

It orbits the Sun in the

semi-major axis of 2.35 AU). Its orbit has a very eccentricity of 0.32 and an inclination of 23° with respect to the ecliptic.[2] The body's observation arc begins with a precovery taken at Palomar Observatory in September 1954, more than 26 years prior to its official discovery observation at Lowell Observatory's Anderson Mesa Station in April 1981.[1]

Rotation period

In December 2005, a rotational

U=3).[6][a]

In April 2010, two nearly identical periods were found by

U=2/3).[10][a][b] While not being a fast rotator
, Levasseur's rotation is near the cohesionless spin-barrier of 2.2 hours.

Diameter and albedo

According to a dedicated survey of Mars-crossing asteroids carried out by the

albedo of 0.239.[5] The Collaborative Asteroid Lightcurve Link assumes a standard for a stony asteroid of 0.20 and calculates a diameter of 6.21 kilometers based on an absolute magnitude of 13.4.[3]

Sizable Mars-crosser

With a diameter of 5.68 kilometers, Levasseur is still one of the smaller "sizable" Mars-crossers (5–15 km). These include 3581 Alvarez (13.69 km) 1065 Amundsenia (9.75 km), 1139 Atami (9.35 km), 3737 Beckman (14.36 km), 1474 Beira (15.46 km), 5682 Beresford (7.33 km), 1011 Laodamia (7.39 km), 1727 Mette (5.44 km), 1131 Porzia (7.13 km), 1235 Schorria (5.55 km), 985 Rosina (8.18 km), 1310 Villigera (15.24 km), and 1468 Zomba (7 km), which are smaller than the largest members of this dynamical group, namely, 132 Aethra, 323 Brucia (former Mars-crosser), 1508 Kemi, 2204 Lyyli and 512 Taurinensis, all larger than 20 kilometers.
