List of future astronomical events

A list of future observable astronomical events, of the classical variety: those seen by eyesight, or happen within the Solar System. These are by no means all events, but only the notable or rare ones. In particular, it does not include all solar eclipses or lunar eclipses unless otherwise notable, as they are far too numerous to list (see below for articles with lists of all these). Nor does it list astronomical events that have yet to be discovered. Some points of the list miss the last date of the events.

9th and 10th millennia

All these dates are in a uniform time scale such as Terrestrial Time. When converted to our ordinary solar time or Universal Time, which is decidedly non-uniform, via ΔT, the dates would be about one day earlier. Because of this difference, these dates have no anniversary relation to historical dates and should not be linked to them. Furthermore, they are only astronomical dates, so they are given in the astronomical format of Year Month Day, which allows them to be ordered.

Notes

1. The eclipse of 2045 will be visible from the United States, producing a path from California to Florida. Some parts of Florida are predicted to experience totality for six minutes, the longest in US history.^{[citation needed]}
2. Exceeding 7 minutes of totality, this will be the first time this has happened in 177 years; the last one occurred on June 30, 1973,^[84] when the Concorde prototype followed the totality spot for 73 minutes.
3. Largest total solar eclipse in the 3rd millennium, with a magnitude of 1.08074^[86]
4. Very close to the theoretical maximum.
5. "Crowning" this series. This is predicted to be the longest eclipse during the current 10,000-year period, from 4000 BC to 6000 AD (eclipse predictions by Fred Espenak, NASA/GSFC.DEPP).^[89]
6. "Crowning" this series.
7. The series from the last total eclipse of the last millennium taken on August 11, 1999.
8. "Crowning" this series.
9. The Solar saros 167 presents eclipses with very similar to those of the Solar saros 145 Archived December 10, 2008, at Wikiwix. For example, the Solar eclipse of July 21, 2726 Archived August 8, 2007, at the Wayback Machine (5 min 43 s), the previous one of the July 31, 2744 in this series of Solar saros 167, would have a pathway very similar to the last one of the last millennium taken on August 11, 1999, one of the series of Solar saros 145. It would happen at a far anniversary of the first step on the Moon by Neil Armstrong, in 1969. It would also be 1 millennium, 2 years, 2 months, minus 1 day (calendar durations) after the historical eclipse of May 22, 1724 (29th of Solar saros 133), which was seen by Jacques Cassini and the king Louis XV. And obviously, this solar eclipse of July 31, 2744 in this series of Solar saros 167, would have a pathway very similar to that of the first "US Solar Eclipse of the 21st century" on August 21, 2017, the following one of the series of Solar saros 145.
