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 depending on the direction. In 2003 the Yarkovsky effect was first observed at work by high-precision radar observations of Golevka.[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).
Golevka approaches Earth to 0.05 AU (7,500,000 km; 4,600,000 mi) in 2046, 0.10 AU in 2069, and 0.11 AU in 2092.[3] On the other hand, Golevka's collision probability with any planet is negligible for at least the next nine centuries.[4] Its orbit is strikingly similar to that of 4179 Toutatis in eccentricity, semi-major axis, and inclination. However, Toutatis is better known due to a close approach to Earth in 2004.
