A montage of Jupiter and its four largest moons (distance and sizes not to scale) There are 95 moons of Jupiter with confirmed orbits as of 5 February 2024. [1] [note 1] This number does not include a number of meter-sized moonlets thought to be shed from the inner moons, nor hundreds of possible kilometer-sized outer irregular moons that were only briefly captured by telescopes. [4]
Montage of Jupiter 's four Galilean moons, in a composite image depicting part of Jupiter and their relative sizes (positions are illustrative, not actual). From top to bottom: Io, Europa, Ganymede, Callisto. The Galilean moons (/ ˌɡælɪˈleɪ.ən /), [1] or Galilean satellites, are the four largest moons of Jupiter: Io, Europa, Ganymede ...
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 only 7% of the Sun's radius. [135] [136] The average distance between Jupiter and the Sun is 778 million km (5.2 AU) and it
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 ...
Solar eclipses on Jupiter occur when any of the natural satellites of Jupiter pass in front of the Sun as seen from the planet Jupiter. [1] For bodies that appear smaller in angular diameter than the Sun, the proper term would be a transit. For bodies that are larger than the apparent size of the Sun, the proper term would be an occultation.
Thus, the Sun occupies 0.00001% (1 part in 10 7) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly 1 millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (0.00047 AU; 44,000 mi), whereas the most distant planet, Neptune, is 30 AU ...
First solar-powered Jupiter orbiter, first mission to achieve a polar orbit of Jupiter. 2011-040A: JUICE: ESA: 14 April 2023 (launch) orbiter enroute 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. [84] Europa Clipper: NASA ...
Sun–Earth L 4. [] L 4 is the Sun–Earth Lagrange point located close to the Earth's orbit 60° ahead of Earth. Asteroid (706765) 2010 TK 7 is the first discovered tadpole orbit companion to Earth, orbiting L 4; like Earth, its mean distance to the Sun is about one astronomical unit.
