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.
For example, the eccentric planet HD 80606 b has an extremely elliptical orbit with a periapsis distance of 0.03 au and apoapsis distance of 0.87 au, and may be a celestial body that is transitioning to a hot Jupiter with an orbital radius of 0.03 au.
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.
It has the third-closest orbit around Jupiter among known moons and was the fifth moon of Jupiter to be discovered, so it is also known as Jupiter V. It is also the fifth-largest moon of Jupiter, after the four Galilean moons. Edward Emerson Barnard discovered the moon on 9 September 1892 and named it after Amalthea of Greek mythology. [10]
HD 149026 b was the first of its kind: [20] HD 149026 b's low volume means that the planet is too dense for a Saturn-like gas giant of its mass and temperature. It may have an exceptionally large core composed of " metals ", or elements heavier than hydrogen and helium: [ 1 ] the initial theoretical models gave the core a mass of 70 times Earth ...
Adrastea (/ æ d r ə ˈ s t iː ə /), also known as Jupiter XV, is the second by distance, and the smallest of the four inner moons of Jupiter. It was discovered in photographs taken by Voyager 2 in 1979, making it the first natural satellite to be discovered from images taken by an interplanetary spacecraft , rather than through a telescope ...
For example, Jupiter has a synodic period of 398.8 days from Earth; thus, Jupiter's opposition occurs once roughly every 13 months. If the orbital periods of the two bodies around the third are called T 1 and T 2 , so that T 1 < T 2 , their synodic period is given by: [ 7 ]
