Uranus Has a Long-Lost Twin

Uranus has always been a pretty lonely planet. The seventh planet from the Sun, this "ice giant" made primarily of ice particles, hydrogen, and helium is relatively unique, drifting around our solar system in an unusual elliptical orbit at a stunning 99 degrees axial tilt. Now, however, researchers are saying that the baby-blue planet has an unlikely twin 25,000 light-years away.
