Asteroid Approach on November 8
Topic: Meteorites, Comets and Asteroids
On Nov. 8th, the asteroid 2005 YU55 will safely fly past Earth slightly closer than the Moon's orbit. Scientists will be watching it from Earth, gathering new data about the small space rock.

Battered Asteroid May Have Warm Core
Topic: Meteorites, Comets and Asteroids
New data from the Rosetta probe indicates that the asteroid 21 Lutetia may have a molten, metallic core.

Comet Elenin Gone But Not Forgotten
Topic: Meteorites, Comets and Asteroids
It appears that the small comet Elenin has broken apart while passing close to the Sun.

Hard Core Meteorite Impact
Topic: Meteorites, Comets and Asteroids
A newly-developed model will help astrobiologists understand the level of death and destruction that could result from a large meteorite striking the Earth.

Spitzer Detects Comet Storm in Nearby Solar System
Topic: Meteorites, Comets and Asteroids
Astronomers have discovered signs of icy bodies raining down in an alien solar system. The system resembles our own solar system during the 'Late Heavy Bombardment' - a period that may have brought water and life-forming ingredients to Earth.

Meteorite CSI
Topic: Meteorites, Comets and Asteroids
Scientists have forensically reconstructed the impact of a meteorite on Earth and how debris was hurled from the crater to devastate the surrounding region. The study indicates that giant meteorite impacts may mimic the behaviour of large volcanic eruptions.

Amateur Skywatchers Spot Near Earth Asteroid Threat
Topic: Meteorites, Comets and Asteroids
Observations coordinated by ESA's space hazards team have discovered an asteroid that will come close enough to Earth to pose a threat.

Triple Asteroid Mash-Up
Topic: Meteorites, Comets and Asteroids
Analysis of fragments of a meteorite that landed in Sudan in 2008 show that its parent asteroid was likely formed from the collisions of three different types of asteroids.

Secrets of Asteroid Minerva and its Moons
Topic: Meteorites, Comets and Asteroids
Observations of Minerva indicate that it may be structurally unique among asteroids.

Proof that Comets Brought Oceans to Earth
Topic: Meteorites, Comets and Asteroids
Scientists have identified 103P/Hartley 2 as the first comet with water similar to Earth's. The findings shed new light on how our planet could have become habitable for life.
