Caption: Comet Hartley 2 can be seen in glorious detail in this image from NASA's EPOXI mission. It was taken as the spacecraft flew by around 6:59 a.m. PDT (9:59 a.m. EDT), from a distance of about 700 kilometers (435 miles). The comet's nucleus, or main body, is approximately 2 kilometers (1.2 miles) long and .4 kilometers (.25 miles) at the "neck," or most narrow portion. Jets can be seen streaming out of the nucleus.
The mission's Medium-Resolution Instrument was used to capture this view. The sun is to the right.
This EPOXI mission image of comet 103P/Hartley 2 was taken right at about the Time of Closest Approach (TCA) using the Medium Resolution Instrument (MRI) and a clear filter. The mid-exposure time was 2010/11/04 13:59 UTC.
