No satellites or robots have ever shown up on Jupiter as far as we know. We have sent our own exploration probes that have passed Jupiter.
There have been no dedicated missions to explore Uranus with satellites or robots. The only spacecraft to have conducted a close flyby of Uranus was Voyager 2 in 1986.
The three robots, known as the Galileo spacecraft, arrived at Jupiter in 1995. They were launched by NASA in 1989 and spent several years traveling through the solar system before reaching their destination. Galileo conducted extensive studies of Jupiter and its moons during its mission.
The only spacecraft to visit Uranus is NASA's Voyager 2 probe. It conducted a flyby of the planet in 1986, providing valuable data and images of Uranus and its moons. There are no known robots or satellites currently on or orbiting Uranus.
To the best of our knowledge, no satellites or robots have directly explored the planet Haumea. Haumea is a dwarf planet located in the Kuiper Belt beyond Neptune, and its distance from Earth makes it challenging to send a mission there. Most of our knowledge about Haumea comes from observations made by telescopes on Earth.
This means Jupiter takes precisely twelve Earth years to orbit the sun.
Only Voyager 2.
Yes, robots have not landed on Saturn itself, but the Cassini spacecraft spent over 13 years studying the planet and its moons before intentionally plunging into Saturn's atmosphere in 2017. No satellites have landed on Saturn.

Neptune's largest moon, Triton, was visited by the Voyager 2 spacecraft in 1989. There are no other dedicated "satellite robots" sent to Neptune's other moons as of current knowledge.

Galileo Galilei is widely believed to be the first to discover that Jupiter has moons, on January 7, 1610. However, some believe that Chinese astronomer Gan De was the first to make that discovery 1971 years earlier.

10,475.8 Jupiter days are in a Jupiter year.
Until quite recently ... maybe within the past 10-15 years or so ... Jupiter was listed as having 12 natural satellites. Today, that number is given as "at least 63".
Some of the satellites and robots that have explored Venus include the Soviet Venera program, which launched various missions between 1961 and 1983. NASA's Magellan spacecraft orbited Venus from 1990 to 1994, mapping its surface with radar. The European Space Agency's Venus Express mission operated from 2006 to 2014, studying the planet's atmosphere and surface.
A year on Jupiter is 11.862615 Earth years.
