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. [60] Europa Clipper: NASA
Jupiter Icy Moons Explorer (JUICE) Jupiter and Ganymede: 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. European Union: Euclid: Earth-Sun L 2 point: Operational: It is ESA's project for a space telescope to study dark ...

Searches for more satellites have been unsuccessful, putting the maximum radius of any other satellites at 90 m (100 yd). [4] Jupiter has 95 moons with known orbits; 72 of them have received permanent designations, and 57 have been named. Its eight regular moons are grouped into the planet-sized Galilean moons and the far smaller Amalthea group ...
Such an orbit can place a satellite in constant sunlight and is useful for imaging, spy, and weather satellites. Frozen orbit: An orbit in which natural drifting due to the central body's shape has been minimized by careful selection of the orbital parameters. Orbit of the Moon: The orbital characteristics of the Moon.
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
The term satellite thus became the normal one for referring to an object orbiting a planet, as it avoided the ambiguity of "moon". In 1957, however, the launching of the artificial object Sputnik created a need for new terminology. [5] The terms man-made satellite and artificial moon were very quickly abandoned in favor of the simpler satellite ...
