Rounded reference values. Rotation is sidereal and differs from the solar day. Giant planets have no solid surface; temperature and gravity use atmospheric reference levels. Some moon counts are omitted because discoveries change them.
Compare with EarthA closer look
Its axis is tilted almost into the plane of its orbit.
Voyager 2 is the only spacecraft to have flown past Uranus.
Atmosphere
Hydrogen, helium, and methane. Methane absorbs red light.
Discovery
Identified as a planet by William Herschel in 1781.
