Dawn is an unmanned NASA space probe.[1] It has orbited and studied the asteroid Vesta, which is in the asteroid belt.[1]

Dawn was launched on September 27, 2007[1][2][3][4] at Cape Canaveral Air Force Station aboard a Delta 7925-H rocket.[2][3] It then travelled to Mars for a gravity assist, making its closest approach to Mars on February 2009.[1]

Next, Dawn set off for Vesta.[1] It went into orbit in July, 2011.[1] In September 2012, Dawn left Vesta and headed for Ceres,[1] a dwarf planet in the asteroid belt. The space probe should start orbiting Ceres in February 2015.[1][4][5] By the time Dawn reaches Ceres, it will have travelled 5.1 billion km.[4]
