first probe to cross the asteroid belt; first Jupiter probe; first man-made object on an interstellar trajectory; now in the outer regions of the Solar System but no longer contactable 1972-012A: Pioneer 11: NASA: 4 December 1974 flyby success went on to visit Saturn 1973-019A: Voyager 1: NASA: 5 March 1979 flyby success went on to visit Saturn ...
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.
Sinope / s ə ˈ n oʊ p iː / is a retrograde irregular satellite of Jupiter discovered by Seth Barnes Nicholson at Lick Observatory in 1914, [1] and is named after Sinope of Greek mythology. Sinope did not receive its present name until 1975; [10] [11] before then, it was simply known as Jupiter IX. It was sometimes called "Hades" [12 ...

USSR Sputnik 2: 31 January 1958: Confirmed existence of the Van Allen radiation belt. USA Explorer 1: 17 March 1958: First use of solar power in space.
Retrograde irregular satellites of Jupiter. Pasiphae orbits Jupiter on a high eccentricity and high inclination retrograde orbit. It gives its name to the Pasiphae group, irregular retrograde moons orbiting Jupiter at distances ranging between 22.8 and 24.1 million km, and with inclinations ranging between 144.5° and 158.3°.

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 ...
