6489 Golevka

6489 Golevka is an Apollo, Mars-crosser and Alinda asteroid, discovered in 1991 by Eleanor F. Helin.

Its name has a complicated origin. In 1995, Golevka was studied simultaneously by three radar observatories across the world: Goldstone in California, Evpatoria in Ukraine (sometimes written Yevpatoriya ), and Kashima in Japan. 'Golevka' comes from the first few letters of each observatory's name.

Golevka is a small object, measuring 0.6×1.4 km. The radar observations revealed that it has a very strange, angular shape that looks different from almost every angle. In 2003 the Yarkovsky effect was first observed at work by high precision radar observations of Golevka. This helped evaluate the asteroid's density (2.7±0.5 g/cm³) and mass (2.10×10¹¹ kg).
