"The Enigmatic Moon: Unraveling its Mysteries, Features, and Significance in Space Exploration"

Before we start our today's topic let ask one question to. Do you know about moonquakes or listening for the first' time? If you are head this term for the first time like me then you came to the right place to know about moonquake. So let's see together.

What is the moon?

The Moon is a large natural object that orbits or travels around, Earth. After the Sun it is the brightest object in the sky

How was the moon formed ?

According to NASA's leading theory of the Moon's origin explains that a Mars-sized celestial body collided with Earth before many years approximately 4.5 billion years ago and this resulted in, debris from both Earth and another body accumulated to form their natural satellite moon. 

In which state was it when it was newly formed?

When the Moon was newly formed, it did not exist in a state we would recognize today. Instead, it was a hot and molten mass of rock and debris. Over time, as it cooled and solidified, the Moon's surface features and characteristics began to develop. So, there was no specific state like a modern celestial body when the Moon was first formed; it evolved over billions of years into its current state.

Why the moon is called the moon?

The word moon is adopted from an Old English word from medieval times that is Mona. Mona shares its origins with the Latin words metric, which means to measure, and mensis, which means month. Now we know that the moon is called the moon because it is used to measure the months.

Is there a quake on the moon?

just like Earthquake, there is a quake on the moon called a moonquake. They were first discovered by the Apollo astronauts. The largest moonquakes are much weaker than the largest earthquakes.

What causes moon quakes?

 > Moonquakes caused when the moon's crust slips and cracks due to the gradual shrinking or “raising” of the moon as it cools. It can also be caused by the Sun, thermal quakes, or by the vibration caused by meteorites.

Types of moon quake:

There are four kinds of Moonquakes till now identified they are-

1. deep moonquakes about 700 km below the surface, probably caused by tides
2. vibrations from the impact of meteorites
3. Thermal quakes caused by the expansion of the frigid crust when first illuminated by the morning sun after two weeks of deep-freeze lunar night; and 
4. Shallow moonquakes only 20 or 30 kilometers below the surface.

Important points:

• The average distance of the moon from Earth  is 384,400 kilometers (km).

• Orbit and Rotation Period: 27.32 Earth Days

• Equatorial Radius: 1,079.6 miles | 1,737.5 kilometers

• Mass: 0.0123 of Earth's (a bit more than 1 percent) 

• Gravity: 0.166 of Earth's (If you weigh 100 pounds (45 kilograms) on Earth, you'd weigh 16.6 pounds (7.5 kilograms) on the moon) 

• Temperature Range: -414 to 253 degrees Fahrenheit (-248 to 123 degrees Celsius)

Importance of moon:

It is very pleasant to see the moon at night as it's very beautiful, along with beauty it is also very important for us and our Earth .

The Moon makes Earth  a more livable planet by moderating our home planet's wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years.

Why the moon is called a natural satellite?

Moons are called natural satellites because they orbit planets. The moon as seen above does orbit the Earth and this is why we call it a natural satellite and not a man-made satellite.

Facts about moon-

• Fact1. Slowly waning: The Moon is slowly moving away from Earth at a rate of about 1.5 inches (3.8 centimeters) per year. This is due to the transfer of angular momentum through tides. 

• Fact 2. The moon is the easiest celestial object to find in the night sky — when it's there.

• Fact 3. We see slightly more than half of the moon from Earth. 

• Fact 4. It would take hundreds of thousands of moons to equal the brightness of the sun.

• Fact 5. A moon with 95 percent illuminated appears half bright as the full moon. 

• Fact 6. Peace of the Moon: The Moon is absolutely calm. It lacks an atmosphere, so there is no medium for sound transmission, which means no sound can be heard on the Moon.

• Fact 7. Footprints will last forever: The footprints of astronauts left on the surface of the Moon by the Apollo missions of the late 1960s and early 1970s will likely remain visible for millions of years due to the absence of wind and erosion .

• Fact 8. Earthrise: During the Apollo 8 mission in 1968, astronauts observed and captured the iconic "Earthrise" photograph, which showed the Earth rising above the moon's horizon. It was a powerful symbol of the unity of our planet.

• Fact 9. Moonquakes: Moonquakes are relatively common, but unlike earthquakes, they can last up to an hour because there is no liquid core to damp the vibrations.

• Fact 10. Alien meteorite: In 2019, a meteorite from another celestial body, possibly a small asteroid or moon, landed on Earth. This was the first time we had confirmed interstellar visitors to our planet.

• Fact 11. Giant impact basins: There are giant impact basins on the Moon, some of which are hundreds of miles wide, formed by ancient asteroid or comet impacts. The South Pole–Aitken Basin is one of the largest and deepest impact basins in the Solar System.

• Fact 12. Mysterious Tidal Locking: The exact reason why the Moon is tidally locked with the Earth, always showing the same face, remains a subject of study and debate among scientists.

• Fact 13. Microgravity art: During the Apollo 15 mission, astronaut David Scott demonstrated the concept of Galileo's theory of free fall by dropping a geologic hammer and a feather together on the Moon. Due to the Moon's microgravity they fell at the same rate, proving the theory.

• Fact 14. Lunar geysers: There is some evidence that water vapor geysers may occasionally erupt from the Moon's surface due to the interaction of solar radiation with water ice in permanently shadowed areas.
