Question

How long would a complete day (both day and night) on Earth be if it did NOT spin on its axis?

Answer 1

If you divide 24 hours by 365 days, you'll see that you're left with about 4 minutes per day. In other words, the Earth rotates on its axis, but it's also orbiting around the Sun, so the Sun's position in the sky catches up by 4 minutes each day
