1. Direct detection of the Yarkovsky effect by radar ranging to ateroid 6489 Golevka

Abstract

Radar ranging from Arecibo, Puerto Rico, to the 0.5-kilometer near-Earth asteroid 6489 Golevka unambiguously reveals a small nongravitational acceleration caused by the anisotropic thermal emission of absorbed sunlight. The magnitude of this perturbation, known as the Yarkovsky effect, is a function of the asteroid's mass and surface thermal characteristics. Direct detection of the Yarkovsky effect on asteroids will help constrain their physical properties, such as bulk density, and refine their orbital paths.

Abstract

Optical and radar observations reveal that 1999 GU3 is subkilometer-sized object with a synodic period of 9.0 days, low visual and radar albedos, and colors more consistent with the ordinarychondrites than the vast majority of main-belt asteroids.

Abstract

We obtained echoes from five NEA's during this period. The following table presents our astrometric results. Each entry gives the time delay or Doppler frequency for echoes from the target's center of mass, received at the specified UTC epoch.
