ELI5: Why does the night sky appear to move slowly even though the earth is rotating at 1,000mph?
gpt
Because mph is the wrong unit. The earth is rotating at 0.0007 rpm, so the stars appear to rotate at the same rate. The minute hand of a clock has an angular velocity 24 times faster than the stars (0.017 rpm), but it still isn't fast enough to be able to see the movement.
