The Dawn's Early Light

This article is about how a spacecraft was reaching its destination as the last shuttle left from Florida last week. The space shuttle should be arriving on the second largest asteroid, Vesta, on July 16. Vesta is about 520 kilometers in diameter and is roughly spherical, similar to a planet, due to its gravity. What also makes this asteroid similar to a planet is that it has layers, a mantle and a core. After a year at Vesta, the spacecraft will then travel on to another asteroid, Ceres, the largest asteroid which is 960 kilometers in diameter. It is due to arrive there in 2015.
