The innards of an asteroid in space have been measured for the first time. Astronomers using a European Southern Observatory telescope have made precise measurements of Asteroid Itokawa's density.
05 February 2014, 06:00 AM ET
By analyzing brightness, as it rotates, astronomers see how asteroid 25143 Itokawa’s surface may be changing and gain clues to its interior. Images collected by Japan’s Hayabusa probe in 2005, plus ESO’s New Technology Telescope, form this animation.
