Title: 13 Surprising Facts About Our Mysterious Lunar Companion
Introduction
The moon has been an endless source of fascination for humans since the dawn of our existence. As we venture into space and explore the final frontier, our enchanting satellite has never failed to inspire awe and wonder. But did you know that there are still more secrets hidden in its mesmerizing and mysterious expanse? Here we uncover 13 surprising facts about the moon that you are not aware of.

1. Opposite Seasons: When it’s summer in the Northern Hemisphere, it’s winter on the lunar surface, and vice versa. The North and South poles experience extremes of heat and cold, which means ice can coexist with molten lava!
2. It doesn’t Spin: The reason we always see the same face of the moon is that it has a synchronous rotation with Earth, meaning its rotational period and orbital period are identical.
3. Perfectly Shaped: The moon’s shape is not just a coincidence. It’s almost a perfect sphere, only about 1% flatter than a perfect sphere.
4. Moonquakes: Just like earthquakes on Earth, there are moonquakes too! These tremors can last for hours, and their seismographs have amazed scientists.
5. Look, no Rocks: The moon’s surface is uniform, without the varied terrain we see on Earth. It’s covered in a layer of dust and rocky debris called regolith.
6. The Highlands: The darkness of the “maria” contrasts against the luminescent “highlands” – mountains on the moon’s surface, which are no less than 12,700 feet (4,000 meters) in height!
7. Mercury and Venus: Apart from Earth, it’s one of the few celestial bodies visible from Earth with the naked eye. However, its apparent visual size is still much smaller than Venus and Mercury!
8. No Atmosphere: The moon has no atmosphere, which means the airless environment allows incredible views of the celestial bodies and impact craters that would be obstructed by a planet’s clouds.
9. The Moon and Earth: The gravitational force between Earth and the Moon forms Earth’s tides, and thanks to its smooth orbit, it’s responsible for the Moon’s synchronous rotation with Earth.
10. Hollow Moon Theory: Some people erroneously believed the moon was hollow due to the lack of observed seismic activity from outside. But with the discovery of moonquakes and creepery mares, the hollow moon theory is debunked.
11. Moon Exploration: The first human landed on the moon in 1969 with NASA’s Apollo 11 mission. Since then, six trips have taken visitors to the moon.
12. Moon Base: NASA’s planned moon base – Artemis Base Camp – is set to house visiting astronauts for the first time by 2024.
13. Lunar Treasure: Finally, it turns out the moon is a treasure trove. It’s laced with a scarce, but valuable element, helium-3, up to ten times more abundant on the Moon than Earth. This isotope could play a crucial role in the development of clean energy technology.
FAQs:
FAQ 1: How much of the moon can we see from Earth?
We can see about 59% of the Moon from Earth, known as the “Phases of the Moon”. The viewing angle changes with the moon’s orbit around the Earth, giving us our phases – New, Waxing Crescent, First Quarter, Waxing Gibbous, Full, Waning Gibbous, Last Quarter, and Waning Crescent.
FAQ 2: Are there any living organisms on the moon?
No, there are no living organisms on the moon because it lacks air, water, and a significant source of heat.
FAQ 3: Why we don’t see stars from the Moon?
Due to the absence of an atmosphere, even the faintest stars are visible from the moon, resulting in lunar skies giving a much brighter overall appearance.
FAQ 4: What causes moonquakes?
Moonquakes are caused by the gravitational interaction of the moon with Earth, which creates small tremors on the moon’s surface. Lunar tectonic activity and meteorite impacts also cause moonquakes.
FAQ 5: Is the moon moving away from Earth?
Yes, the moon is moving away from Earth at a rate of about a centimeter a year, caused by tidal bulges.
FAQ 6: Can the moon affect humans’ behavior?
There’s no scientific evidence suggesting that the phases of the moon affect humans’ behavior. The belief that madness is related to the lunar phase is known as the lunar effect; however, the scientific community does not recognize this.
Impressive and mysterious, the moon continues to amaze us with its unexplored depths and fascinating secrets. Indeed, one giant leap for mankind began on that one small step to the moon’s surface so many years ago, and we are not done exploring just yet.
