2862 Vavilov, provisional designation 1977 JP, is a stony background

Sergey Ivanovich Vavilov.[2]

Orbit and classification

Vavilov is located in the dynamical region of the

It orbits the Sun in the inner main-belt at a distance of 1.9–2.5 AU once every 3 years and 3 months (1,193 days). Its orbit has an eccentricity of 0.11 and an inclination of 3° with respect to the ecliptic.[1]

The body's observation arc begins with its first identification as 1931 DY at Lowell Observatory in February 1931, more than 46 years prior to its official discovery observation at Nauchnij.[11]

Physical characteristics

Vavilov is an assumed stony

spectral type
for members of the Flora family.

Rotation period

In February 2006, a rotational

With a period above 500 hours, Vavilov is one of only a few dozen slow rotators with such an extreme spin rate currently known to exists.

Diameter and albedo

According to the surveys carried out by the Japanese

albedo between 0.21 and 0.404.[6][7][8][9]

The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the Flora family's parent body – and calculates a diameter of 7.82 kilometers based on an absolute magnitude of 12.7.[3]

Naming
