A tiny chunk of stone that looks like nothing else ever seen in the solar system might be even weirder than scientists thought. The Hypatia stone was found in southwestern Egypt in 1996. It was hardly more than a pebble, just 1.3 inches (3.5 centimeters) wide at its widest and a smidge over an ounce (30 grams) in weight. But analysis revealed that the stone (dubbed "Hypatia" for a fourth-century female mathematician and philosopher) fit into no known category of meteorite.

Through sheer serendipity, this odd triple-star planet popped up first.
