A transit of Jupiter across the Sun as seen from an outer planet (Saturn, Uranus or Neptune) takes place when the planet Jupiter passes directly between the Sun and the outer planet, obscuring a small part of the Sun's disc for an observer on the outer planet. During a transit, Jupiter can be seen from the outer planet as a small black disc moving across the face of the Sun. Deimos transits the Sun, as seen by Mars Rover Opportunity on March 4, 2004 The word transit has two meanings in astronomy: A transit is the astronomical event that occurs when one celestial body appears to move across the face of another celestial body, as seen by an observer at...

Jupiter's satellites could theoretically be seen at the same time, but their angular diameter would only be about 1" at Saturn and even less for more distant planets, and they would therefore be very hard to see. The angular diameter of an object as seen from a given position is the diameter measured as an angle. ...

The most interesting case would be a transit of Jupiter from Saturn. Unfortunately, no such transit occurs between about 1625 and 2475, and according to the calculations of Albert Marth in 1886, no such transit will in fact occur for 2000 years in the past and 2000 years in the future. This is a pity, since Jupiter would block more of the Sun from Saturn than any other transit involving two planets in the solar system. Jupiter's angular diameter is about 40.5" and the Sun's angular diameter is about 3.2' from Saturn, and Jupiter would therefore block 4.4% of the Sun's light.

The Jupiter-Saturn synodic period is 19.85887 years (7253.45 days). The Jupiter-Uranus synodic period is 13.81195 years (5044.81 days). The Jupiter-Neptune synodic period is 12.78219 years (4668.69 days). The orbital period is the time it takes a planet (or another object) to make one full orbit. ...

The mutual inclination of the orbits of Jupiter and Saturn is 1.25°. The mutual inclination of the orbits of Jupiter and Uranus is 0.70°. The mutual inclination of the orbits of Jupiter and Neptune is 0.94°. Inclination is one of the six orbital parameters describing the shape and orientation of a celestial orbit and is the angular distance of the orbital plane from the plane of the reference (usually planets equator or the ecliptic), stated in degrees. ...

Note: the images linked to in the following table do NOT take into account the finite speed of light. This can have an appreciable effect, for instance one-way light travel times are: 122 min (Jupiter-Uranus) and 165 min (Sun-Uranus) for the 1997 transit of Jupiter from Uranus.

The images correspond to a hypothetical observer at the center of Saturn or Uranus or Neptune. Since planets like Saturn have a large radius, there will be some effect of parallax between the planet's center and its north or south pole. However, the effect would be very small and would amount to only a couple of percent or less of the angular diameter of the Sun. Parallax (Greek: παραλλαγή (parallagé) = alteration) is the change of angular position of two stationary points relative to each other as seen by an observer, due to the motion of said observer. ...
