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

The radar observations revealed that it has a very strange, angular shape that looks different depending on the direction.

[2] Between 1991 and 2003, the small force of the Yarkovsky effect caused a shift of 15 kilometers (9.3 mi) from what would be expected based on only gravitational interactions.

[2] This helped evaluate the asteroid's bulk density (2.7 ± 0.5 g/cm3) and mass (2.10×1011 kg).

[4] Its orbit is strikingly similar to that of 4179 Toutatis in eccentricity, semi-major axis, and inclination.
