The length of a day on Uranus as measured by Voyager 2 is 17 hours, 14 minutes. [49] Uranus was shown to have a magnetic field that was misaligned with its rotational axis, unlike other planets that had been visited to that point, [50] [53] and a helix-shaped magnetic tail stretching 10 million kilometers (6 million miles) away from the Sun.

For celestial bodies in the solar system, the synodic period (with respect to Earth and the Sun) differs from the tropical period owing to Earth's motion around the Sun. For example, the synodic period of the Moon 's orbit as seen from Earth , relative to the Sun , is 29.5 mean solar days, since the Moon's phase and position relative to the Sun ...
Sun · Saturn · Uranus · Neptune · Pluto Pluto's orbital period is about 248 years. Its orbital characteristics are substantially different from those of the planets, which follow nearly circular orbits around the Sun close to a flat reference plane called the ecliptic .
As of September 2012, sunlight took 16.89 hours to get to Voyager 1 which was at a distance of 121 AU. The apparent magnitude of the Sun from the spacecraft was −16.3 (about 30 times brighter than the full Moon). [76] The spacecraft was traveling at 17.043 km/s (10.590 mi/s) relative to the Sun.
No spacecraft other than Voyager 2 has flown by our seventh planet from the sun. Alone but certainly unique, Uranus rotates at a nearly 90-degree angle and is surrounded by 13 icy rings.
The possibility of sending the Cassini spacecraft to Uranus was evaluated during its mission extension planning phase. [52] It would have taken about twenty years to get to the Uranian system after departing Saturn, and these plans were scrapped in favour of remaining at Saturn and eventually destroying the spacecraft in Saturn's atmosphere.
