Eli5: why does the last part of the sunset goes so quickly?

Question

Like the moment the sun is about to vanish goes by so fast. In thirty seconds you can see the last part of the sun go under while the rest of the sunset seems to last way longer.

In: 5

Answer 1

The sun is always moving that fast, you just don’t notice. The sun is arou mbd half a degree in the sky, the sky is 180 degrees which means the sun moves its own size every 4 minutes. So the last 1/8 of the sun would be expected to disappear in 30 seconds.
