Visiting a Comet

The EPOXI spacecraft pays a quick visit to Comet Hartley on November 4, 2010. Click to play.

They’re calling it a “peanut with jets”…Comet Hartley 2, discovered 26 years ago by astronomer Malcolm Hartley, received a brief but fascinating visit today by NASA’s EPOXI spacecraft at 10:01 am EDT. Images were received on Earth half an hour later, and I assembled these initial 5 close-ups into the rough animation above. (Click to play.)

The Sun is to the right in these images and the comet’s jets can be seen issuing from numerous sites on the end facing it.

β€œThis is a type of moment that scientists live for, to get new results in such a dramatic fashion. The images are clear, taken as spacecraft was approaching, then as it swung past and moved away.”

– Don Yeomans, JPL

One and a quarter miles long, Hartley-2 is the fifth comet to have been visited by a spacecraft. It’s estimated that it will last another 700 years or so before disintegrating.

Read more on this dramatic rendezvous on Universe Today, or visit the EPOXI site for more images from the mission.

Also, Emily at The Planetary Society has made an animation of this as well….check it out!

    Anyone know approximately where in the solar system this comet is when these pics were taken?


    1. J. Major says:

      I’m not sure where it was, but I do know it was about 23 million miles from here. Of course, with comets that could be in any direction….they don’t always travel along the plane of the rest of the solar system.

        Thanks! I didn’t even have the 23 million miles to compare to! It’s a bit ol’ solar system!
