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.

| February 28, 11,575 AD | A simultaneous annular solar eclipse and transit of Mercury. |
| September 17, 13,425 AD | A near-simultaneous transit of Venus and Mercury. |
| 13,727 AD | Vega becomes the North Star. |

| 20,346 AD | Thuban becomes the North Star.[circular reference] |
| 27,800 AD | Polaris again is the North Star. |
| 27,000 years | The eccentricity of Earth's orbit will reach a minimum, 0.00236 (it is now 0.01671). |
| 66,270 AD | Sirius becomes the South Star at 1.6° of the south celestial pole, due to the combination of precession and its own proper motion. |
| 67,173 AD | The planets Mercury and Venus will both cross the ecliptic at the same time. |
| July 26, 69,163 AD | A simultaneous transit of Venus and Mercury. |
| 70,000 years | Estimated time for Comet Hyakutake to return to the inner Solar System, after having travelled in its orbit out to its aphelion 3410 A.U. from the Sun and back. |
| 93,830 AD | Sirius becomes once again the South Star, but at 2.3° of the south celestial pole. |
| March 27 and 28, 224,508 AD | Respectively, Venus and then Mercury will transit the Sun. |

| 571,741 AD | A simultaneous transit of Venus and the Earth as seen from Mars. |
| 6 million years | Estimated time for Comet C/1999 F1 (Catalina), one of the longest period comets known to return to the inner Solar System, after having travelled in its orbit out to its aphelion 66,600 AU (1.053 light-years) from the Sun and back. |
| 230 million years | Prediction of the orbits of the Solar System's planets is impossible over time spans greater than this, due to the limitations of Lyapunov time. |
| 100-300 million years | Estimated time for Saturn's rings to disappear. |
| ~600 million years | Last total solar eclipse |
