An ice giant knocked completely on its side, enduring 42-year winters.
Uranus rolls around the Sun on its side like a bowling ball. Because of this tilt, each pole faces 42 years of continuous sunlight followed by 42 years of pitch-black winter, creating unusual seasonal shifts.
Verified science answered in plain, accessible language.
Uranus has an axial tilt of 97.8 degrees, likely caused by a cataclysmic collision with an Earth-sized protoplanet early in solar system history.
Methane in Uranus' upper atmosphere absorbs red wavelengths of sunlight while reflecting back cool cyan and green light into space.
Yes! Even though Neptune is farther from the Sun, Uranus holds the record for the coldest recorded atmospheric temperature (-224°C / -371°F) because it emits virtually no internal heat.
