Dawn’s interplanetary trajectory (January 2015)
Dawn’s interplanetary trajectory (January 2015) Dawn’s interplanetary trajectory (in blue). The dates in white show Dawn’s location every Sep. 27, starting on Earth in 2007. Note that Earth returns to the same location, taking one year to complete each revolution around the sun. When Dawn is farther from the sun, it orbits more slowly, so the distance from one Sep. 27 to the next is shorter. NASA / JPL-Caltech
