In planetary astronomy, a centaur is a small Solar System body that orbits the Sun between Jupiter and Neptune and crosses the orbits of one or more of the giant planets. . Centaurs generally have unstable orbits because of this; almost all their orbits have dynamic lifetimes of only a few million years, [1] but there is one known centaur, 514107 KaŹ»epaokaŹ»awela, which may be in a stable ...
Trident is a space mission concept to the outer planets proposed in 2019 to NASA's Discovery Program. [3] [4] The concept includes flybys of Jupiter and Neptune with a focus on Neptune's largest moon Triton.
These probes make Jupiter the most visited of the Solar System's outer planets as all missions to the outer Solar System have used Jupiter flybys. On 5 July 2016, spacecraft Juno arrived and entered the planet's orbit—the second craft ever to do so. Sending a craft to Jupiter is difficult, mostly due to large fuel requirements and the effects ...
Voyager 2 flew by Uranus and was the first spacecraft to visit it. Neptune 25 August 1989 4389 days (12 yr, 6 days) Voyager 2 flew by Neptune and was the first spacecraft to visit it. Voyager 1: Jupiter 5 September 1977 5 March 1979 547 days (1 yr, 6 mo, 1 d) Voyager 1 flew by Jupiter and returned the first detailed images. [94] Saturn 12 ...
Timelapse of Voyager 2 approaching Jupiter. The plains of Pluto, as seen by New Horizons after its nearly 10-year voyage. Remotely guided space probes have flown by all of the observed planets of the Solar System from Mercury to Neptune, with the New Horizons probe having flown by the dwarf planet Pluto and the Dawn spacecraft currently orbiting the dwarf planet Ceres.
The orbits of Solar System planets are nearly circular. Compared to many other systems, they have smaller orbital eccentricity. [70] Although there are attempts to explain it partly with a bias in the radial-velocity detection method and partly with long interactions of a quite high number of planets, the exact causes remain undetermined. [70] [74]
NASA's Juno spacecraft recently flew by Jupiter, collecting crucial data -- and the best look we've gotten at the planet in a very long time. This is the closest photo of Jupiter anyone has seen ...
Voyager 1 · Jupiter · Io · Europa · Ganymede · Callisto The trajectory of Voyager 1 through the Jupiter system. Voyager 1 began photographing Jupiter in January 1979. Its closest approach to Jupiter was on March 5, 1979, at a distance of about 349,000 kilometres (217,000 miles) from the planet's center. [37]
