Most asteroids with moonlets started off as solitary bodies that split in two while sunbathing, new computer simulations suggest. Once thought to be rare, dozens of binary asteroid systems – kilometer-sized rocks orbited by small moonlets – have been found in the main belt between Mars and Jupiter since the first asteroid pair was spotted by the Galileo spacecraft in 1993.
