Pawlowia (

minor planet designation: 1007 Pawlowia), provisional designation 1923 OX, is a background asteroid from the central regions of the asteroid belt, approximately 20 kilometers in diameter. It was discovered on 5 October 1923, by Soviet astronomer Vladimir Albitsky at the Simeiz Observatory on the Crimean peninsula.[11] The asteroid was named after Russian physiologist and Nobelist Ivan Pavlov.[2]

Orbit and classification

Pawlowia is a non-

semi-major axis of 2.71 AU). Its orbit has an eccentricity of 0.11 and an inclination of 3° with respect to the ecliptic.[1]

The asteroid was first imaged on a precovery taken at Lowell Observatory in December 1906. The body's observation arc begins at Simeiz on 30 October 1925, or 25 days after its official discovery observation (discovery record not listed).[11]

Physical characteristics

In the

SMASS classification, Pawlowia is a K-type asteroid, which are common among members of the Eos family and known for their intermediate albedo.[1]

Rotation period

In September 2003, a tentative rotational

U=1).[10] As of 2018, no secure period has been obtained.[9]

Diameter and albedo

According to the surveys carried out by the Japanese

albedo between 0.080 and 0.145.[4][5][6][7][8]

The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and consequently calculates a much larger diameter of 32.03 kilometers based on an absolute magnitude of 11.2.[9]

Naming

This minor planet was named after Russian biologist Ivan Pavlov (1849–1936), who was awarded the Nobel Prize in Physiology or Medicine in 1904 (see list of laureates). Pavlov is best known for his research on classical conditioning (Pavlov's dog).[2]

The official naming citation was mentioned in

H 96). The lunar crater Pavlov was also named in his honor.[2]
