Ultracool dwarf stars orbit each other in less than a day

Scientists have discovered a record-breaking binary star system consisting of two ultra-cool dwarf stars so close together that they complete an orbit in less than a day.

The stars are separated by only about 1.5 million miles, about 1% of the distance between Earth and sun, which means that a year for these stars lasts only 17 hours. This makes the star system the densest ultracool dwarf binary ever found.
