The primary observation target is Jupiter itself, although limited images of some of Jupiter's moons have been taken and more are intended. [5] JunoCam successfully returned detailed images of Ganymede after Juno's flyby on June 7, 2021, [ 6 ] with further opportunities including planned flybys of Europa on September 29, 2022, and two of Io ...
Time-lapse sequence from the approach of Voyager 1 to Jupiter in 1979, showing the motion of atmospheric bands, and the circulation of the Great Red Spot. The black spots that appear are shadows cast by Jupiter's moons. Jupiter's Great Red Spot rotates counterclockwise, with a period of about 4.5 Earth days, [24] or 11
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.
Atmospheric super-rotation is a phenomenon where a planet's atmosphere rotates faster than the planet itself. This behavior is observed in the atmospheres of Venus , Titan , Jupiter , and Saturn. Venus exhibits the most extreme super-rotation, with its atmosphere circling the planet in four Earth days, much faster than the planet's own rotation ...
In astronomy, the rotation period or spin period [1] of a celestial object (e.g., star, planet, moon, asteroid) has two definitions. The first one corresponds to the sidereal rotation period (or sidereal day), i.e., the time that the object takes to complete a full rotation around its axis relative to the background stars (inertial space).
