Jupiter

An impact by a giant asteroid probably shifted Ganymede's axis. Jupiter's moon, the largest in the Solar System, shows signs of a major impact in the past. New research suggests that this impact, which likely occurred 3 billion years ago, could have been by an asteroid with a diameter of about 300 kilometers (299 kilometers), about 20 times larger than the one that hit Earth 65 million years ago. The impact would have been powerful enough to tilt Ganymede’s axis, pointing its north pole away from Jupiter (pictured in this artist’s impression). Image credit: HIRATA Naoyuki.
