 The moon, the earth and the sun: this is a frame grab from a flash video of the Cassini-Huygens probe, prepared by Erich Karkoschka using data from that probe's descent imager and spectral radiometer instruments. It shows the moon and earth transiting the sun on January 14, 2005 as Cassini-Huygens left the inner solar system for a rendezvous with Saturn's moon Titan.
The moon is the tiny dot center left, the earth is center right. Between and above them lie sunspots on the solar surface. This image was the first I've ever seen that really let me grasp visually the relative size and distance of these two bodies. The sun is huge, even though it's some 90+ million miles more distant, giving a clue to its true and enormous size. The moon orbits a bit less than 240,000 miles from earth. Love those photo robots... |
