Caption: This EPOXI mission image of comet 103P/Hartley 2 was taken 5 days from Encounter (E-5d) using the Medium Resolution Instrument (MRI) and a clear filter. Science team co-Investigator Dr. Lucy McFadden combined four successive one-minute exposures to make this single image. The mid-exposure time was 2010/10/30 09:22 UTC. The comet was 1.06 AU from the Sun and 0.04 AU (5.5 million km) from the spacecraft.
