List of future astronomical events

A list of future observable astronomical events. These are by no means all events, but only the notable or rare ones. In particular, it does not include 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. And some points of the list miss the last date of the events.

2090 September 23 Total solar eclipse in the United Kingdom. The next total eclipse visible in the UK follows a track similar to that of August 11, 1999, but shifted slightly further north and occurring very near sunset.

2094 April 7 Mercury occults Jupiter; it will be very close to the Sun and impossible to view with the naked eye.
2096 The dwarf planet 2015 RR245 is expected to make its closest approach to the Sun.[33]
2100 March 24 Polaris appears furthest North. Polaris's maximum apparent declination (taking account of nutation and aberration) will be 0.4526° from the celestial north pole.[34]

1The 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.
2Exceeding 7 minutes of totality, this will be the first time this has happened in 177 years; the last one occurred on June 30, 1973,[132] when the Concorde prototype followed the totality spot for 73 minutes.
3Largest total solar eclipse in the 3rd millennium, with a magnitude of 1.08074[133]
4Very close to the theoretical maximum.

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 ?T, 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.

Calendar projections

This assumes that these calendars continue in use, without further adjustments.

(Some of these are not astronomical events.)

Years from now Gregorian
date		 Event
57 2077 Beginning of the 16th century in the Islamic calendar.
80 2100, March 1 First century non-leap year since 1900.
80 2100, March 14 March 14 (which will be February 29 in the Julian calendar), the difference between the Julian calendar and the Gregorian calendar reaches 14 days. Since 14 is divisible by 7, this will be the first time in history since its inception that the Gregorian calendar has the same day of the week for each day of the year as the Julian calendar. This will last until February 28, 2200 of the Gregorian Calendar.
194 2214 Rosh Hashanah will fall on October 6 for the first time.
219 2239 September 29 The Year 6000 begins in the Hebrew Calendar.
240 2260 Rosh Hashanah will fall on September 6 for the last time.
265 2285 Unless changes are made in the religious calendar, the Western Easter will fall on March 22 for the first time since 1818, the earliest possible date on which Easter can occur.[154]
780 2800, March 1 The Revised Julian and Gregorian calendars will differ by a day.
≈2750 4772 October 13 The Mesoamerican Long Count calendar, assuming a turnover value of 20 b'ak'tuns, will require a sixth order.
≈4000 6009 The first Strobogrammatic numbered year since 1961.
10,000

 The Gregorian calendar will have drifted by about 10 days in relation to the seasons.[155]
10,871 June 10, AD 12,892 In the Hebrew calendar, due to a gradual drift in relation to the solar year, Passover will fall on the northern summer solstice (it has historically fallen around the spring equinox).[156]
18,853 AD 20,874 The lunar Islamic calendar and the solar Gregorian calendar will share the same year number. After this, the shorter Islamic calendar will slowly overtake the Gregorian.[157]
25,000
—
 The Tabular Islamic calendar will be roughly 10 days out of sync with the Moon's phases.[158]
46,880 March 1, AD 48,901[note 1] The Julian calendar (365.25 days) and Gregorian calendar (365.2425 days) will be one year apart.[159]
The Julian day number (a measure used by astronomers) at Greenwich mean midnight (start of day) is 19 581 842.5 for both dates.

Notes
  1. The series from the last total eclipse of the last millennium taken on August 11, 1999.
  2. The saros 167 presents eclipses with very similar to those of the saros 145. 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 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 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 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 saros 167, would have a pathway very similar to the one of the first "US Solar Eclipse of the 21st century" on August 21, 2017, the following one of the series of saros 145.
