Explanation: A day is just under 11 minutes long on 1998 KY26, a 30 meter wide,
fast-spinning, water-rich asteroid. This computer simulated view of its lumpy surface has a
resolution of about 3 meters and is based on radar and optical observations (click on the
image for a series of surface views). The observations were made shortly after the discovery
of the diminutive world which passed within about 800,000 kilom |
