[4] [5] It was initially thought to be Jupiter's outermost known moon until recovery observations disproved this in 2020. [ 6 ] S/2003 J 2 is about 2 km (1.2 mi) in diameter, and orbits Jupiter at an average distance of about 20,600,000 kilometers (20.6 gigametres (0.138 AU )) in roughly 600 days, at an inclination of around 149° to the ...
3-hour timelapse showing rotation of Jupiter and orbital motion of the moons. Jupiter is the only planet whose barycentre with the Sun lies outside the volume of the Sun, though by 7% of the Sun's radius. [130] [131] The average distance between Jupiter and the Sun is 778 million km (5.20 AU) and it completes an orbit every 11.86 years.
Like all irregular moons of Jupiter, S/2018 J 4's orbit is highly variable over time due to gravitational perturbations by the Sun and other planets. [5] On average, S/2018 J 4's orbit has a semi-major axis of 16.3 million km (10.1 million mi), an eccentricity of 0.18, and a very high inclination of 50° with respect to the ecliptic .
HD 80606 b (also Struve 1341 Bb or HIP 45982 b) is an eccentric hot Jupiter 217 light-years from the Sun in the constellation of Ursa Major. HD 80606 b was discovered orbiting the star HD 80606 in April 2001 by a team led by Michel Mayor and Didier Queloz. [2] With a mass 4 times that of Jupiter, it is a gas giant.
A major issue with sending probes to Jupiter is the amount of radiation to which a space probe is subjected, due to the harsh charged-particle environment around Jupiter (for a detailed explanation see Magnetosphere of Jupiter). For example, when Pioneer 11 made its closest approach to the planet, the level of radiation was ten times more ...
Thebe / ˈ θ iː b iː /, also known as Jupiter XIV, is the fourth of Jupiter's moons by distance from the planet. It was discovered by Stephen P. Synnott in images from the Voyager 1 space probe taken on March 5, 1979, while making its flyby of Jupiter. [7] In 1983, it was officially named after the mythological nymph Thebe. [8]
Kepler-419b is a hot Jupiter, an exoplanet that has a radius and mass near that of the planet Jupiter, but with a much higher temperature. It has a temperature of 505 K (232 °C; 449 °F). [ 2 ] It has a mass of 2.5 M J and a radius of 0.96 R J .
The Himalia group is bunched together near the top of the diagram. An object's position on the horizontal axis indicates its distance from Jupiter. The vertical axis indicates its inclination. Eccentricity is indicated by yellow bars illustrating the object's maximum and minimum distances from Jupiter. Circles illustrate an object's size in ...
