On Friday 27 July the longest lunar eclipse of the century will take place, a blood moon as they call it. The sun, Earth and moon align perfectly, putting the moon in the Earth’s shadow. The moon will be totally eclipsed by the Earth for one hour and 43 minutes and the red colouring is a result of sunlight refracting through the Earth’s atmosphere. Here are some interesting fun facts about the Moon. A lunar eclipse occurs when the Earth is between the Sun and the Moon. The Earth and moon rotate together, so we always see the same side of the moon. The Moon orbits the Earth every 27.3 days. The entire surface of the moon could fit in the continent of Asia. No astronaut has walked on the surface of the moon since 1972. The Earth’s tides are largely caused by the gravitational pull of the Moon. If There Was No Moon, Our Days Would Have Been Only 6-8 Hours Long. The moon’s atmosphere is like a vacuum, so there’s no sound. Driving A Car At A Speed Of 60 MPH, You Can Reach The Moon In Only About 6 Months. The Moon Is Not Round Like Earth But Similar To An Egg In Shape.
