So far only one spacecraft has ever flown by Neptune and that was Voyager II in 1989. Neptune is extremely far away from the Sun, and getting there would be highly expensive and take many years to get there, so it doesn't look likely we'll be getting any more Neptune probes soon.
The Voyager I and the Voyager II are the only space probes to visit Neptune. They landed in the 1980s.
Not exactly. The Voyager 2 space probe did a flyby of Neptune, but since it never actually orbited the planet, it can't be considered a satellite. Neptune does not have a solid surface, so nothing could ever land on it.
It can be seen and weighed (it has a satellite) and visited (a probe went by).
The Voyager 2 space probe did a flyby of Neptune on August 25th 1985, beaming back images and data to Earth. Nothing can land on Neptune because it is a gas giant. Gas giants do not have a solid surface.
It may be possible in the future, but today we are not able to travel that far.
Voyager 2 did not land on Neptune, it made a flyby.
Only one space probe went to or flew by Neptune which was Voyager 2.
The first space probe was the Luna I by the United Soviet Socialist Republic. It did a flyby of the moon in 1959
Voyager 2 was never on Neptune, but rather did a close flyby. During this flyby, Voyager 2 studied Neptune's atmosphere and the planet's largest Moon, Triton. It also discovered 6 new moons orbiting the planet.
It is a telescope placed in space (like the hubble telescope). When placed in space the telescope does not have to "look" through the earth's atmosphere so its images are not destorted.
No, but a space probe called New Horizons is on its way for a flyby.
Yes or else how would we know anything about it
