Solar eclipses on Uranus
|This article needs additional citations for verification. (November 2011)|
Solar eclipses on Uranus occur when any of the natural satellites of Uranus passes in front of the Sun as seen from Uranus. Eclipses can occur only near a solar ring plane-crossing of Uranus (equinox), occurring approximately every 42 years, last crossing being in 2007/2008.
For bodies which appear smaller in angular diameter than the Sun, the proper term would be a transit. For bodies which are larger than the apparent size of the Sun, the proper term would be an occultation.
All other satellites of Uranus are too small and/or too distant to produce an umbra.
At this distance from the sun, the sun's angular diameter is reduced to a tiny disk about 2 arcminutes across. Here are the angular diameters of the moons large enough to fully eclipse the sun : Cressida, 6-8'; Desdemona, 6-7'; Juliet, 10-12'; Portia, 9-13'; Rosalind, 4-5'; Belinda, 6-8'; Puck, 6-8'; Miranda, 10-15'; Ariel, 20-23'; Umbriel, 15-17'; Titania, 11-13'; Oberon, 8-9'.
