Abstract:
We present resolved near-infrared images of near-Earth Asteroid 2004 XP14, obtained with the adaptive optics system on Keck II during July 2006. This is the first time a near-Earth asteroid has been directly imaged from the ground. Our result illustrates the capabilities of adaptive optics and complements radar and spectral observations.
