THE TILTED GIANT

Uranus is the seventh planet — an ice giant unlike any other. Knocked over long ago, it orbits the Sun almost completely on its side, giving it the most extreme seasons in the Solar System. It is the coldest planet, wrapped in serene cyan methane haze.

A WORLD ON ITS SIDE

Uranus is tilted a staggering 98° — almost certainly knocked over by a colossal ancient impact. It effectively rolls around the Sun on its side, so each pole spends 42 years in continuous sunlight, then 42 years in darkness. The most extreme seasons anywhere.

THE COLDEST PLANET

Despite Neptune being further out, Uranus is the coldest planet, plunging to −224°C. Unlike the other giants it gives off almost no internal heat, so its atmosphere is eerily calm and clear — a still, frozen cyan world of water, methane and ammonia ices.

FAINT, DARK RINGS

Uranus has 13 rings, far darker and narrower than Saturn's — made of charcoal-black chunks of ice and rock. Invisible to early astronomers, they were discovered only in 1977. A subtle crown for the planet that does everything differently.

“The world that fell on its side and kept on going — the frontier rewards those who move differently.”
