Uranus passage from Neptune
A Uranus transit in front of the Sun as seen from Neptune takes place when Uranus directly crosses the Neptune - Sun line of sight . During the transit , Uranus can be seen as a small disk that moves slowly over the surface of the sun. The process of this central transit lasts about 42 hours.
It is the rarest of all possible planetary transits in our solar system because of the long period of 172 years (for a planetary transit from Neptune) during which there is a very small apparent diameter of the sun (1.07 arc minutes , near the limit of the human visual resolution ) is seen from Neptune and the mutual inclination of the two orbits of 1.5 °, which is smaller than that of most pairs of planets.
The next passage of Uranus from Neptune is in October 38,172 AD.
