This wikipedia page is just great, and includes such hits as:
- 1 million years: Highest estimated time until the red supergiant star Betelgeuse explodes in a supernova. The explosion is expected to be easily visible in daylight.
- 1.4 million years: Gliese 710 passes within 1.1 light years of the Sun, potentially disturbing the Solar System's Oort cloud and increasing the likelihood of a comet impact in the inner Solar System.
- 10 million years: The widening East African Rift valley is flooded by the Red Sea, causing a new ocean basin to divide the continent of Africa.
- 11 million years: The moon Phobos collides with the surface of Mars.
Makes you think in a slightly longer time frame than what's for dinner on Tuesday.
