Often paired with latitude, longitude is the crucial coordinate that tells us exactly how far east or west we are from a starting point. What is a Meridian? meridian longitude

We apply similar coordinate systems to map the surfaces of Mars and the Moon. Pilots and captains use these coordinates to chart
