What planets have been landed on and whats the farthest anyone has gone in space?

Mars is the most explored planet, and only our two nearest neighbors, Venus and Mars, have been visited by humans. Landing on another planet is a difficult task, with numerous attempts at landing ending in failure.

Mercury is a possible landing target, but it would be difficult given the speeds involved and Mercury's close proximity to the Sun. The Messenger probe orbited Mercury before crashing into its surface, so it wasn't really a landing.

Because they are gas giants or ice giants, the outer planets cannot be reached by land because they lack true surfaces.

The Moon is the only body on which a manned spacecraft has made a landing, and it is also the furthest point in space that any human has ever traveled. The furthest distance would have been reached while in orbit around the Moon's far side.

Humans have set foot on Mars, Venus, and the Moon; they have also traveled beyond the solar system with unmanned spacecraft such as Voyager 1. The Moon represents the greatest distance that humans have ever traveled in space.
