On 25 August, in Voyager 2 's last planetary encounter, the spacecraft swooped only 4,950 km (3,080 mi) above Neptune's north pole, the closest approach it had made to any body since it left Earth in 1977. At that time, Neptune was the farthest known body in the Solar System.
Following a course correction in 1987, Voyager 2 ' s closest approach to Neptune occurred on August 25, 1989. [ 58 ] [ 34 ] Through repeated computerized test simulations of trajectories through the Neptunian system conducted in advance, flight controllers determined the best way to route Voyager 2 through the Neptune–Triton system.
Closest approach at 01:21 UTC on 26 August 1981. Flew past Iapetus, Titan, Dione, Mimas, Enceladus, Tethys and Rhea at long distances. Later flew past Uranus and Neptune.

Neptune is currently approaching perihelion (closest approach to the Sun) and has been shown to be heating up, with increased atmospheric activity and brightness as a consequence. Combined with technological advancements, ground-based telescopes with adaptive optics are recording increasingly more detailed images of it.
Satellites in geostationary orbit. From the list in the first section, these are the closest known asteroids per year that approach Earth within one lunar distance.More than one asteroid per year may be listed if its geocentric distance [note 1] is within a tenth of the lunar distance, or 0.10 LD.
