The Details
19, 2026, revealing auroras shaped magnetic field. Uranus has the strangest magnetosphere in the Solar System.
It is tilted and offset from the planet’s rotation axis (and this planet already rolls around the Sun nearly on its side), which means auroras move across the surface in complex ways. Better understanding Uranus will give us insight into ice-giant planets and help us better characterize giant planets outside our Solar System.
Why This Matters
