This is a list of all spacecraft landings on other planets and bodies in the Solar System, including soft landings and both intended and unintended hard impacts. The list includes orbiters that were intentionally crashed, but not orbiters which later crashed in an unplanned manner due to orbital decay. Colour key:

Moons (not directly orbiting the Sun) and planets are not minor planets and thus are not included in the table below. Flyby; first asteroid visited by a spacecraft.
READ MOREPioneer 10. NASA''s first spacecraft to visit the outer planets, Pioneer 10 was designed as a 21-month mission to Jupiter, yet lasted more than 30 years. After its Jupiter encounter in 1973, it continued beyond the solar system, sending its last signal to Earth in January 2003 from a distance of 7.6 billion miles. Explore.

READ MORE5 · Space exploration - Solar System, Probes, Missions: From the start of space activity, scientists recognized that spacecraft could gather scientifically valuable data about the various planets, moons, and smaller bodies in the solar system. Both the United States and the U.S.S.R. attempted to send robotic missions to the Moon in the late 1950s. The

READ MOREIt could be possible for humans to walk on 3 planets of the Solar system besides Earth: Mercury, Venus, and Mars. These are rocky planets with solid surfaces unlike the outer planets like Jupiter, Saturn, Neptune, and Uranus that are mostly made out of gas. You would still need to find a way to protect yourself against all the other

READ MOREPlanet Neptune Overview. Dark, cold and whipped by supersonic winds, giant Neptune is the eighth and most distant major planet orbiting our Sun. More than 30 times as far from the Sun as Earth, Neptune is not visible to the naked eye. In 2011, Neptune completed its first 165-year orbit since its discovery. The planet''s rich blue color comes
READ MOREOne day on Mars lasts about 37 minutes longer than an Earth day. A year on Mars is almost twice as long as a year on Earth. Gravity on Mars is about one-third of the gravity on Earth. If you weigh 100 pounds on Earth, you would weigh 38 pounds on Mars. Mars has two moons: Phobos and Deimos.
READ MOREBoth believe that we might get there in the 2030s. The next most favorable window for sending humans on a relatively quick round-trip to Mars would be in 2033, but it''s unclear whether politics
READ MOREFour robotic spacecraft have visited Saturn. NASA''s Pioneer 11 provided the first close look in September 1979. NASA''s twin Voyager 1 and Voyager 2 spacecraft followed up with flybys nine months apart in 1980 and 1981. Each flyby revealed intriguing details about the ringed giant world, but it wasn''t until the international Cassini mission arrived []

READ MOREHow many planets have been visited by probes? Since the 1990s, a total of 16 minor planets – various asteroids, dwarf planets, and Kuiper belt objects – have been visited by space probes. Note that moons (not directly orbiting the Sun), comets and planets are not minor planets and thus are not included in the table below.
