3635 Kreutz, provisional designation 1981 WO1, is a

Mars-crosser from the innermost regions of the asteroid belt, approximately 3 kilometers in diameter. It was discovered on 21 November 1981, by Czech astronomer Luboš Kohoutek at the Calar Alto Observatory in southern Spain.[3]

Orbit and classification

Kreutz is a

Hungaria group.[4]

It orbits the Sun at a distance of 1.6–1.9 AU once every 2 years and 5 months (878 days). Its orbit has an

precoveries were taken, and no prior identifications were made.[3]

Physical characteristics

In the

SMASS classification, Kreutz is characterized as a common stony S-type asteroid.[1][4]

Slow rotator

U=2).[6]

As most asteroids have a much shorter rotation period of 2 to 20 hours, Kreutz'es period of 280 hours is among the Top 200 slow rotators known to exist.

Diameter and albedo

According to the survey carried out by the

albedo of 0.269,[5] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 3.41 kilometers using an absolute magnitude of 14.7.[4]

With a mean-diameter of approximately 3 kilometers, Kreutz is one of the smaller mid-sized Mars-crossing asteroids. It is assumed that there are up to 10 thousand Mars-crossers larger than 1 kilometer.[8] The largest members of this dynamical group are 132 Aethra, 323 Brucia, 2204 Lyyli and 512 Taurinensis, which measure between 43 and 25 kilometers in diameter.
