Does Asteroid Vesta Have a Moon?

You might think of asteroids as isolated bodies tumbling alone through space, but it's entirely possible for these old "loners" to have companions. Indeed, 19-mile-wide Ida, 90-mile-wide Pulcova, 103-mile-wide Kalliope, and 135-mile-wide Eugenia each have a moon. And 175-mile-wide Sylvia has two moons. Measuring 330 miles across, Vesta is much larger than these other examples, so a "Vesta moon" is entirely possible.

Dawn Spacecraft Provides New Data from Asteroid

Scientists working with NASA's Dawn spacecraft reveal new data and imagery captured by the probe as it approaches the Vesta asteroid at a science briefing held at NASA Headquarters in Washington on June 23. Dawn is scheduled on July 16 to begin orbiting Vesta 9,900 miles above the surface of the asteroid belt's second-largest object.

NASA Hosts Preview of Visit to Large Asteroid

NASA will host a news briefing at 11 a.m. PDT (2 p.m. EDT) on Thursday, June 23, to discuss the Dawn spacecraft's year-long visit to the large asteroid Vesta. The mission is expected to go into orbit around Vesta on July 16 and begin gathering science data in early August.
The event will be held at NASA Headquarters in Washington and will be broadcast live on NASA Television.

Asteroid Vesta: The Key to Understanding Our Solar System?

Vesta also moves at a little faster rate although it is a smaller asteroid so this may average out in the long run to the same speed as it take Earth to rotate once on its axis, Vesta averages one turn every 5.34 hours as it take Earth 24 hours to make one turn.
Vesta is a very interesting little asteroid in that it has a lot of the same characteristics as does Earth. Vesta is very diverse and is really the only asteroid out there to have a light and a dark area on its surface such as does our moon. If you look at the moon at night whether through a telescope or by the naked eye, not only will you see a face in the moon but that face is really just the light and dark areas on the surface.

NASA Spacecraft Captures Video of Asteroid Approach

Scientists working with NASA's Dawn spacecraft have created a new video showing the giant asteroid Vesta as the spacecraft approaches this unexplored world in the main asteroid belt.
The video loops 20 images obtained for navigation purposes on June 1. The images show a dark feature near Vesta's equator moving from left to right across the field of view as Vesta rotates. Images also show Vesta's jagged, irregular shape, hinting at the enormous crater known to exist at Vesta's south pole.
