NASA's Lucy asteroid-hopping probe captures 1st snapshot of space rock 'Dinky' (photo)
NASA's Lucy spacecraft just sent home an impressive glimpse of the smallest asteroid target on its 12-year agenda to study intriguing space rocks.
Asteroids are space rocks thought to be the remains left over from the formation of the solar system. They range in size from tiny (the size of a car or so) to truly giant, with at least one - Ceres - gaining dwarf planet status. In our solar system, billions of asteroids are in the asteroid belt, a region around the sun between the orbits of Mars and Jupiter. Others stray from this region, and can potentially post an impact threat to the Earth. At least one interstellar asteroid, called 'Oumuamua, has passed through our solar system.
