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. 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.
