What does Earth's moon and several of the larger asteroids hovering around our solar system have in common? Well, according to NASA, they've both been blasted under a bombardment of asteroids in the past.
Half the size of a football field, asteroid 2012 DA14 will give the Earth a "record-setting" close shave, passing closer to our planet than many satellites when it buzzes by later this month, NASA scientists announced.
Two to three billion years ago, a carbon-rich object crashed into the asteroid Vesta and formed dark blemishes on its surface, according to scientists working on NASA's Dawn mission.
NASA's Dawn satellite, which has surveyed the Asteroid Vesta for over a year, has gathered data which suggests the presence of liquid flow on the airless rock.
The NASA Dawn spacecraft discovered hydrated materials that left wide coloration on the giant asteroid.
