The
Hidden and Little-Known Facts about the Moon The moon is an astronomical body that has fascinated man since time immemorial. It is a constant presence in our night sky and has been the center of myth, inspiration, and scientific exploration for centuries. Despite our long history of fascination with the moon, there are still many little-known facts about it that people are not aware of. The Moon is not Round Contrary to popular belief, the moon is not a perfect sphere. It is slightly flattened at the poles and bulges at the equator, making it an oblate spheroid shape. Scientists believe that this shape is the result of the gravitational pull of the Earth on the moon's surface. The Moon Used to be Closer to the Earth The moon is moving away from Earth at a rate of about
3.8 centimeters (
1.5 inches) per year. It is estimated that about
4.5 billion years ago, the moon was only about one-third of its current distance from Earth. As it moves farther away, the moon's gravitational pull on the Earth will weaken, causing the length of a day on Earth to become longer. The Moon is Responsible for the Earth Tides The gravitational pull of the moon on the Earth causes the oceans and seas to bulge outward, creating the tides we experience daily. These tides are not only limited to water bodies, but also influence the Earth's crust, causing it to bulge and create what is known as solid Earth tides. The Moon has a Day and Night Cycle Although the moon does not have an atmosphere or highly active geological processes like the Earth, it does experience a day and night cycle. Due to the moon's slow rotation compared to its orbit around the Earth, one day on the moon (the time it takes for the moon to rotate once) is the same as one month on Earth (the time it takes for the moon to orbit around Earth once). The Moon Has Been Visited Six Times The moon has been visited by humans only six times, all of which were part of the Apollo missions conducted by NASA in the early 1970s. The last time humans visited the moon was in 1972 during the Apollo 17 mission. The Moon Has a Surface Temperature Range The moon's surface temperature can range from a scorching 126 degrees Celsius (260 degrees Fahrenheit) during the day to a freezing -173 degrees Celsius (-280 degrees Fahrenheit) at night. This huge temperature range is due to the moon's lack of atmosphere and insulation, which allows heat to escape rapidly into space. In Conclusion The moon remains an enigmatic and fascinating celestial body that continues to surprise us with its unusual characteristics and little-known facts. Despite its proximity to Earth and our many attempts to explore it, there is still much we do not know about the moon, leaving a vast frontier of scientific exploration and discovery to be carried out in the future.
