Mission: investigating Jupiter and Saturn, and the moons of these planets. Its continuing data feed offered the first direct measurements of the heliosheath and the heliopause. It is currently the furthest man-made object from Earth, as well as the first object to leave the heliosphere and cross into interstellar space.
First solar-powered Jupiter orbiter, first mission to achieve a polar orbit of Jupiter. 2011-040A: JUICE: ESA: 14 April 2023 (launch) orbiter en route mission to study Jupiter's three icy moons Callisto, Europa and Ganymede, eventually orbiting Ganymede as the first spacecraft to orbit a satellite of another planet.

If undisturbed for 296,000 years, Voyager 2 should pass by the star Sirius at a distance of 4.3 light-years. [5] Voyager 1 – launched in September 1977, flew past Jupiter in 1979 and Saturn in 1980, making a special close approach to Saturn's moon Titan. The probe passed the heliopause at 121 AU on August 25, 2012, to enter interstellar space ...
A montage of Jupiter and its four largest moons (distance and sizes not to scale) There are 95 moons of Jupiter with confirmed orbits as of 5 February 2024. [1] [note 1] This number does not include a number of meter-sized moonlets thought to be shed from the inner moons, nor hundreds of possible kilometer-sized outer irregular moons that were only briefly captured by telescopes. [4]
The Himalia group is a group of prograde irregular satellites of Jupiter that follow similar orbits to Himalia and are thought to have a common origin. [ 1 ] The known members of the group are (in order of increasing distance from Jupiter):
The names need to meet certain constraints in order to be approved by the International Astronomical Union, which oversees all names for objects in space and features on their surfaces.Jupiter's ...

Irregular moons are probably minor planets that have been captured from surrounding space. Most irregular moons are less than 10 kilometres (6.2 mi) in diameter. The earliest published discovery of a moon other than Earth's was by Galileo Galilei, who discovered the four Galilean moons orbiting Jupiter in 1610. Over the following three ...
