The two spacecraft that have apparently escaped the Sun's gravity force and have now passed into outer space are the inter-stellar space probes Pioneer 10, launched in 1972 and Voyager 1 launched in 1977.
Yes, many spacecraft have explored beyond Mars. For example, the Voyager probes have traveled beyond our solar system, while spacecraft like New Horizons have flown past Pluto. Additionally, the Parker Solar Probe is currently studying the Sun up close.
A spacecraft left earth in late 1957 and returned in early 1958. Other than human spacecraft, no alien space craft has ever left or come to visit our planet, that we know of. It is possible some alien space craft may have visited earth millions of years ago. It is highly unlikely any craft has done so within the past few centuries.
Humans have visited the Moon, Mars, Venus, and multiple spacecraft have traveled to Jupiter, Saturn, Neptune, and Pluto. However, manned missions have only reached the Moon and Mars.
One can resolve surface details of Mars through a good amateur telescope. Olympus Mons, Vallis Marineris, and the polar ice caps which expand and recede through the martian seasons. Neptune is much further away, a somewhat featureless gas giant, with a low albedo. We have landed numerous spacecraft on Mars, but have not sent anything to Neptune specifically (that I recall).
Most famously, it was voyager 1 and 2 that explored these outer gas planets and have given us so much information. Other probes have been sent to these gas giants, but these are the the probes that visited all four gas giants between them.
i would take it as a no because i cannot find a website that says it or it hasn't so i would say no. no spacecraft has ever landed on or flown past neptune
None. Voyager 2 has flown past it though.
The "Voyager 2" spacecraft.
There are no man-made satellites or robots of Neptune. The space probe "Voyager 2" flew past Neptune, in 1989.
Only one spacecraft has visited Neptune: NASA's Voyager 2 probe, which made a flyby of the planet in August 1989. Voyager 2 provided our first close-up images and scientific data of Neptune and its moons.
