What is the furthest planet man has managed to reach with a probe?

Has the probe actually landed on these planets or just passed by?|||Neptune, as fly-by.





The furthest landing was Mars.





You can't land on Jupiter and Saturn, as they are gas giants and Uranus and Neptune are a bit hard to reach currently|||neptune|||Voyager Two went past Neptune but no,no probes. Incidentally the planets of the solar system are a bore past Mars,they are all gas balls,but the 35 or so moons of the outer s.s. are of almost unimaginable beauty and variety.


As to probes,so far Luna (our moon) was the first,Mars many times now,venus twice by the Russians, Martian moons not sure,but we recently landed a probe on one of the moons of Saturn,really sent back great pics.|||Neptune.





The planet was visited once by Voyager 2, an unmanned robot probe from Earth, which flew within 3,100 miles of Neptune in 1989.|||Mars was the furthest landing next furthest was Venus. Landing a probe on venus is the equivalence of shooting an arrow from Wriggly Field and hitting home plate at Dodgers stadium.|||Probes have visited all of the planets except Pluto (which isn't considered a planet anymore).


The New Horizon's probe is already on its way to Pluto. It's scheduled to arrive in 2015. It's a long way out there.





From Memory, I know that probes have landed on Mars and Venus. The Huygen's probe landed on Saturn's moon, Titan.


There have been probes sent to comet's and asteroids.





The farthest probe is voyager 1 which has gone far past the orbit of Pluto.|||Just to correct Zeno and Winterman97.





Firstly, the Soviets have many more than 2 landers on Venus.


7 operational Veneras, 2 working VeGas.





Secondly, the european Huygens probe successfully landed on Titan.





Sure, Titan's not a planet, but it's the most distant lander we've sent anywhere.
