Eclipse Facts The moon’s shadow moves at 1700 km/hour (1,048 mi/hr) .
Maximum totality is approximately 7 ½ minutes. Every place on Earth will see a total solar eclipse about every 400 years. Solar eclipses occur more frequently than lunar eclipses ( by 5:3). There must be at least two solar eclipses every year. They can be total or partial Seven eclipses per year is the maximum: 4 solar, 3 lunar (1982, predicted 2485).
