Some amazing photographs of an asteroid


Investors Business Daily reports:

NASA's Dawn spacecraft, the first ever to orbit an object in the main asteroid belt, has provided striking latest images of the asteroid Vesta, the second-most largest in the asteroid belt.

. . .

The full-frame image of the rocky world was taken at a distance of 3,200 miles (5,200 kilometers). The latest images that go all the way around Vesta are revealing the first surface details of the giant asteroid.




Vesta, the brightest object in the asteroid belt as seen from Earth, turns on its axis once every five hours and 20 minutes. The giant asteroid is also thought to be the source of a large number of meteorites that fall to the blue planet.

"Now that we are in orbit around one of the last unexplored worlds in the inner solar system, we can see that it's a unique and fascinating place," said Marc Rayman, Dawn's chief engineer and mission manager at NASA's Jet Propulsion Laboratory in Pasadena, Calif.

. . .

Launched in September 2007, the Dawn spacecraft has travelled 1.7 billion miles (2.8 billion kilometers) so far. It has been captured by Vesta's gravity, and now the distance between the asteroid and the spacecraft is 1,800 miles (2,900 kilometers). From Earth, they are approximately 114 million miles (184 million kilometers) away.

The Dawn spacecraft will depart for Ceres in July 2012 and will arrive in 2015.

"second-most largest"

Either my grammar sense is failing me or that isn't quite the proper way to phrase that.
