About this Image

This is a radar image of near Earth asteroid "2001 EC16" made by transmitting a signal at 13 cm wavelength from Arecibo and using the GBT to detect the reflection off the asteroid. The asteroid is roughly 100 meters in size and was only 0.02 AU away (7 lunar distances). These observations show it to be slightly elongated and has a rotation period of several days.

Investigator(s):  Donald Campbell, Jean-Luc Margot, Lynn Carter, and Bruce Campbell
