Earth Spin - Flinders
Earth Spin
This photograph was taken down at Flinders on the Mornington Peninsula in South Eastern Victoria, Star trails reflect Earth’s rotation, or spin, around its axis. The Earth makes a complete rotation relative to the backdrop stars in a period of about 23 hours and 56 minutes. So, as seen from Earth, all the stars go full circle and return to the same place in the sky after this period of time, which astronomers call a sidereal day – a revolution with respect to the stars.
