I was curious about this question too so I tried to find a list of comparable risks. Wikipedia has a list: https://en.wikipedia.org/wiki/Template:Global_catastrophic_r...

The solar flare risk (at ~1% per year [1]) seems much more likely than many of the other items there. Supervolcanos, pandemics, war, and AI also seem like salient risks, but we probably shouldn't worry about e.g. gamma ray bursts or asteroids.
