No person was on a planet that was not earth, only the moon
No spacecraft from Earth has ever landed on Neptune.
It is the spacecraft voyager 2 , it is the only spacecraft to visit Neptune, and travel further.
No voyager 2 or two was the only spacecraft to visit Neptune.
voyager 2 was the first spacecraft to see Neptune's rings
Not yet. And there never will be a spacecraft landing on Neptune. The reason being, because Neptune is a gas giant, it has no solid surface for a spacecraft to land on. Neptune is also freezing cold. Electronic equipment such as a spacecraft would freeze up and malfunction in its atmosphere and most likely end up being consumed by the exposed molten ammonia core.
yes
Voyager 2 is the only spacecraft to have visited Neptune, reaching it on August 25, 1989.
There have been no astronauts that have gone to Neptune. Nor is there any space exploration projects or programs called Neptune that I am aware of.
neptune's rings were discovered by Voyager 2 spacecraft in 1989
Voyager 2 is the only spacecraft to visited Neptune.
Neptune isn't dense enought (not solid enought ground) to stand on so it couldn't so it just flew by and there were 2 voyagers that went out when the planets were aligned in a perfect way to easily get from on to another
some people went up to space to expolre the outer of it so ya people do go in neptune
