April 2008 At present the only planet in our solar system that has not been visited (either by an orbiting spacecraft or flyby spacecraft) has been the recently planet downgraded body of Pluto. There is a mission currently in motion to visit this distant outpost.
Neptune was the last planet to be visited by the space probe called Voyager II. It was launched by NASA and the probed flew past the planet in 1989.
The Mariner10 space probe and the Mercury Messenger space probe.
A planet's gravity affects the trajectory of a space probe by pulling it towards the planet, causing the probe to alter its course. The probe's speed and direction can be influenced by the planet's gravity, leading to changes in its orbit or flight path. Scientists must account for the planet's gravitational pull when planning the probe's trajectory to ensure it reaches its intended destination.
The only probe that has reached Neptune so far was Voyager 2.
All of the eight planets have been visited or orbited by space probes.
Pluto was the only planet not visited by a space mariner space probe.

No humans have ever been to Uranus. Voyager 2 is the only space probe that has visited it.
Venus was the first planet on which a space probe landed.
Pluto is one such planet that has not yet been reached by a space probe.
the megellan space probe was sent to venus.
The Mariner10 space probe and the Mercury Messenger space probe.
The Space Probe Galileo was put into orbit around the planet Jupiter
The first planet to be explored by a space probe is Venus. Hope this helps. : )
mars
Pluto. That is now a dwarf planet. :)
The space probe made fascinating discoveries when it encountered a planet inhabited by creatures that reproduce.
