2591 Dworetsky, provisional designation 1949 PS, is a stony asteroid from the outer region of the asteroid belt, approximately 13 kilometers in diameter.
The asteroid was discovered on 2 August 1949, by German astronomer
Heidelberg Observatory in southern Germany.[8] It was later named after British/American astronomer Michael Dworetsky.[2]
Orbit and classification
Dworetsky orbits the Sun in the outer main-belt at a distance of 2.8–3.1 AU once every 5.03 years (1,839 days). Its orbit has an eccentricity of 0.04 and an inclination of 2° with respect to the ecliptic.[1]
Physical characteristics
The asteroid has been characterized as a common
PanSTARRS' photometric survey.[7]
Dworetsky has a
NEOWISE mission.[4][5] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20, and calculates a diameter of 15.6 kilometers, based on an absolute magnitude of 11.5.[3]
