| Astronomical predictions for the 22nd century
| |
| | |
| * There will be 239 lunar eclipses.
| |
| * A total solar eclipse exceeding 7 minutes of totality will occur on June 25, 2150. This will be the first time this has happened in 177 years; the last one occurred on June 30, 1973 when the Concorde prototype followed the totality spot during 73 minutes.
| |
| But eclipse fans of this epoch will not have to wait nearly so long for it to happen again, as on July 5, 2168 an eclipse with 7 minutes and 26 seconds of totality will occur. Lastly, on July 16, 2186 an eclipse of 7 minutes and 29 seconds (close to the theoretical maximum) will occur. This is predicted to be the longest eclipse during the 8,000 year period from 3000 BC to AD 5000 (eclipse predictions by Fred Espenak, NASA/GSFC.DEPP). All three long-duration eclipses are a part of the same Saros series, Saros 139.
