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.

The last was on July 7, 1959, and the next will occur on October 21, 3187, although some sources claim it will occur on October 6, 2271. 2047 July A METI message called Teen Age Message sent from the 70-metre Eupatoria Planetary Radar will arrive at its destination, 47 UMa. 2048 February 29 There will be a rare full moon on a leap day; this event happens roughly once every century. The next full moon on a leap day will not occur until February 29, 2124.2052 December 6The closest supermoon of the century will occur.2053 August 29A Total Penumbral Lunar Eclipse will occur, the first since 2006.2057 This year will see the very rare occurrence of two total solar eclipses in a single calendar year (on January 5 and December 26). The last time this occurred was 1889. The next time it will occur is 2252. 2060 October 22 Periodic comet 15P/Finlay will pass from Earth. 2061 July 28 Halley's Comet reaches its perihelion, the closest point to the Sun—the last return reached its perihelion on February 9, 1986. 2062 May 10 Transit of Mercury. 2063 Triple conjunction Mars-Uranus. 2065 November 11 Transit of Mercury 2065 November 22 At 12:45 UTC, Venus will transit in front of Jupiter. It will be very difficult to observe from Earth, because the elongation of Venus and Jupiter from the Sun at this time will be only 7 degrees. This event will be the first occultation of a planet by another since January 3, 1818; however, the next will occur less than two years later, on July 15, 2067. 2066 Triple conjunction Jupiter-Uranus. 2067 July 15At 11:56 UTC, Mercury will occult Neptune. This rare event will be very difficult to observe from Earth's surface, because of the constant low elongation of Mercury from the Sun, and the magnitude of Neptune always under the limit of visibility with the naked eye. 2067 October A METI message Cosmic Call 1 sent from the 70-metre Eupatoria Planetary Radar arrives at its destination, HD 178428. 2069 A METI message, Cosmic Call 1, sent from the 70-metre Eupatoria Planetary Radar in 1999, arrives at its destination, 16 Cyg A. 2070 February The Teen Age Message, an Active SETI message sent in 2001 from the 70-metre Eupatoria Planetary Radar, arrives at its destination, the star HD 197076. 2076 July Dwarf planet 90377 Sedna will reach its perihelion of 76 AU from the Sun. (JPL#34/Soln.date: 2021-Apr-13) 2079 August 11 Mercury occults Mars, the first since at least 1708. 2083 A star system known as "V Sagittae" is expected to go nova this year (+/- 11 years). 2084 November 10 Transit of Earth as seen from Mars, the first and the only one in this century. 2085 November 7 Transit of Mercury 2088 October 27 Mercury transits in front of Jupiter for the first time since 1708, but very close to the Sun and impossible to view with the naked eye. 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. Maximum duration in Cornwall will be 2 minutes and 10 seconds. Same day and month as the eclipse of September 23, 1699.2092The trans-Neptunian object will make its closest approach to the Sun of 34 AU. (JPL#21/Soln.date: 2023-Feb-09) 2094 April 7 Mercury occults Jupiter; it will be very close to the Sun and impossible to view with the naked eye. 2100 March 24 Polaris appears furthest North. Polaris' maximum apparent declination (taking account of nutation and aberration) will be 0.4526° from the celestial north pole.
