The long orbital period of Neptune means that the seasons last for forty Earth years. [110] Its sidereal rotation period (day) is roughly 16.11 hours. [12] Because its axial tilt is comparable to Earth's, the variation in the length of its day over the course of its long year is not any more extreme.
One day on Neptune is only 16 hours long, while one day on Earth is 24 hours. 98. Buzz Lightyear’s original name was going to be Lunar Larry. 99. Giant pandas eat around 28 pounds of bamboo each ...
The radio instruments on board found that Neptune's day lasts 16 hours and 6.7 minutes. Neptune's rings had been observed from Earth many years prior to Voyager 2 's visit, but the close inspection revealed that the ring systems were full circle and intact, and a total of four rings were counted. [4] Voyager 2 discovered six new small moons ...
The first one corresponds to the sidereal rotation period (or sidereal day), ... period around a star or another body during one day. ... Neptune: 0.67125 days [3] 0 ...
The Great Dark Spot (also known as GDS-89, for Great Dark Spot, 1989) was one of a series of dark spots on Neptune similar in appearance to Jupiter's Great Red Spot. In 1989, GDS-89 was the first Great Dark Spot on Neptune to be observed by NASA's Voyager 2 space probe. Like Jupiter's spot, the Great Dark Spots are anticyclonic storms.
Four years ago, astronomers noticed the abundant clouds on Neptune had largely disappeared. Telescope data may have helped researchers figure out why. Neptune’s clouds have disappeared, and ...

A mean solar day (what we normally measure as a "day") is the average time between local solar noons ("average" since this varies slightly over a year). Earth makes one rotation around its axis each sidereal day; during that time it moves a short distance (about 1°) along its orbit around the Sun.
