Asteroid Revealed as More Earth-like

A NASA probe that has been visiting an asteroid since July has recorded images scientists say is proof the asteroid has a mineral make up more like that of Earth or Mars than a typical asteroid. Images from the Dawn space probe show differences in rock composition on the Vesta asteroid that are evidence of it's transition from asteroid to terrestrial-like planet.

NASA Readying Giant Antennae to Take Photos of Passing Asteroid

Asteroid 2005 YU55 is scheduled to skirt Earth on Nov. 8, giving astronomers an unparalleled opportunity to make observations about the space rock. Over four hundred yards across, the asteroid is large enough to cause damage on a regional scale if it were to make contact. Luckily, it will just miss Earth, whizzing past at the decidedly cozy distance of 201,700 miles - closer than our own Moon.

Asteroid 21 Lutetia Revealed as Probably a Protoplanet

Ongoing analysis of information gathered by the European Space Association's Rosetta orbiter suggests that a 75-mile-long, 47-mile-wide body named 21 Lutetia, formerly thought to be an asteroid, may actually be a dwarf planet, or protoplanet, leftover from the violent interactions during the early days of our solar system.
