Uranus rolls around the Sun on its side like a giant tilted barrel, likely knocked over by a massive collision billions of years ago. That extreme tilt means its north pole gets 42 straight years of sunlight, followed by 42 years of darkness.
It was the first planet ever discovered using a telescope, spotted by William Herschel in 1781 — before that, no one knew it existed at all. Today we know it has 27 moons and 13 faint rings made of dark, dusty material, all quietly orbiting on their side right along with it.
