Summary

Description
English: Earth physically rotates in 23hours 56min relative to distant stars – a Sidereal Day, BUT it takes 24hours to rotate relative to the Sun – a Solar Day

The difference? Earth orbits the Sun, so the Sun appears to move (down, in the vid), which means Earth needs +4mins to catch up!
