[3] Kreutz is a Mars-crossing asteroid, a member of a dynamically unstable group between the main belt and the near-Earth populations, crossing the orbit of Mars at 1.666 AU.
[1][4] In November 2012, a rotational lightcurve of Kreutz was obtained from photometric observations by American astronomer Brian Warner at his Palmer Divide Observatory (716) in Colorado.
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Kreutz measures 2.94 kilometers in diameter and its surface has an 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.
[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.
This minor planet was named after Heinrich Kreutz (1854–1907), German astronomer at the Kiel Observatory and editor of the journal Astronomische Nachrichten, known for his study of bright sungrazing comets.
