1. Gamma Ray Bursts
GRB's from exploding nearby stars ca potentially damage our ozone layer. The mass extinction that occurred 440 million year ago was possibly because of a GRB pointed at Earth.
2. Asteroid Attack
As Asteroid hitting Earth could potentially aipe out a large number of species-just like the one that killed the dinosaurs.
3. Rogue Planet
Rogue planets are planets that do not orbit start and wander lonely in space. A rouge planet can enter the solar system any time & either hit Earth or alter its orbit.
4. High Energy Solar Flare
Although solar flares wouldn't cause any direct harm to life on Earth, it can wipe our technology and cause blackouts. Recovering from such a catastrophe would not be easy.
5. Wandering Black Holes
Just like rogue planets, there are lonely black holes wandering in space destroying that comes in their path. Such an event would not only destroy life but also the entire planet(Although chances are very low).
