Robotic spacecraft are unmanned vehicles sent into space to explore celestial bodies, perform scientific research, or gather data. They are controlled remotely from Earth and equipped with various instruments and cameras to carry out their missions. Robotic spacecraft have been used to study planets, moons, asteroids, and other objects in our solar system.
As of September 2021, the Jovian system moon Ganymede has been probed by the Galileo spacecraft and the Juno spacecraft. The European Space Agency's upcoming JUICE (JUpiter ICy moons Explorer) mission, set to launch in 2022, will also study Ganymede in detail.
Depends on whether you say Pluto is a planet or not. If you say it isn't, then there are no planets that haven't been visited by a spacecraft. If you say it is, then there is one that hasn't been visited yet, but one is on the way.
There are many planets in our solar system that have not been visited by a spacecraft. As of now, the planet Uranus has not been visited by any spacecraft.
Yes, Mars has been explored by several satellites and spacecraft. Missions like NASA's Mars Reconnaissance Orbiter and the Mars rover missions, such as Curiosity and Perseverance, have provided valuable data and images of the planet's surface. These missions have helped scientists study Mars' geology, atmosphere, and potential for past or present life.
No spacecraft has been sent specifically to study Europa, but several spacecraft that have observed Jupiter also spent time observing Europa. Planned to launch around 2020, the Europa Jupiter System Mission will send 2 to 4 spacecraft to Jupiter, with one spacecraft dedicated to studying Europa: the Jupiter Europa Orbiter.
Jupiter is a gas giant with no solid surface, so no physical objects or structures have been found on Jupiter. However, the planet has been extensively studied by spacecraft and telescopes, leading to discoveries of its atmosphere, magnetosphere, and moons.

Currently no clear pictures if any dwarf planet exist, as none have been visited by a spacecraft. In 2015, however, the New Horizons spacecraft will fly by Pluto, and the Dawn spacecraft will enter orbit around Ceres.
Controlled landings by probes or spacecraft have been achieved on the Moon, Venus, and Mars.

As of yet, there have been no manned Mars spacecraft at all.

The outer planets in our solar system have many moons orbiting around them. They also have rings, with Saturn being the most well-known for its extensive ring system. Additionally, the outer planets have a variety of spacecraft that have been sent to study them, such as the Galileo spacecraft for Jupiter and the Cassini spacecraft for Saturn.
