Montage of planets and some moons that the two Voyager spacecraft have visited and studied. It is the only program that visited all four outer planets. A total of nine spacecraft have been launched on missions that involve visits to the outer planets; all nine missions involve encounters with Jupiter, with four spacecraft also visiting Saturn.
Voyager 2 started taking navigation images of Neptune in May 1988. [3] Voyager 2 's observation phase proper of Neptune began 5 June 1989, the spacecraft officially reached the Neptunian system on 25 August, and data collection ceased on 2 October. [4] Initially it was planned to use a trajectory that resulted in Voyager 2 passing around 1,300 ...

Neptune has long been known to have white clouds circling it, but images of the furthest planet in the solar system have shown this changing over time - the most recent image, taken by the Hubble ...
2000 FE 8 is part of a group of trans-Neptunian objects that orbit in a 2:5 resonance with Neptune. [6] That means that for every five orbits that Neptune completes, 2000 FE 8 makes only two. [ 3 ] Several other objects are in the same orbital resonance, the largest of which is (84522) 2002 TC 302 .
Telescope data may have helped researchers figure out why. Four years ago, astronomers noticed the abundant clouds on Neptune had largely disappeared. Telescope data may have helped researchers ...
