Comet ISON from STEREO

Comet ISON, still intact on November 21, entered the view of the STEREO-A spacecraft's HI-1 camera. This animated field also captures periodic Comet Encke, Mercury, and Earth. The Sun is just out of frame to the right, the source of the solar wind. From STEREO's position in space, Earth is the most distant of these objects, orbiting beyond the Sun.
