How long is the winter on Uranus?
Added 2023-03-18 00:00:01 +0000 UTCFor nearly a quarter of the Uranian year (equal to 84 Earth years), the Sun shines directly over each pole, leaving the other half of the planet plunged into a long, dark winter. Uranus is a ball of mostly hydrogen and helium. Absorption of red light by methane in the atmosphere gives the planet its bluish color.
