One of my favorite cable channels is the National Geographic channel. I really like gaining knowledge especially in science and history, and National Geographic discuss both of them. One of my favorite series of NG channel is the Naked Science. It discusses things with heavy science explanation and they perfectly digest every subject including the Universe.

I had watched this episode that discussed about the Earth’s moon. The show started on the origin of the moon, where the moon came from. Our solar system has been created by rocks that merged by the strong gravitational pull of the star (sun). These rocks orbiting around the sun collided with each other until they formed big rocks and became planets. These planets gained their own gravity which attracted smaller rocks that became their moon.Planet Earth has only one moon (lunar), unlike other planets with multiple satellites (moon) such as Jupiter, Saturn, etc. At first, our moon was dozens of times closer to earth. It appears so big and affected the planet tremendously, such as the waves at the sea. Eons ago, the waves on the sea can reach up to thousands of feet, as high as a multi-story building. This happened because of a strong gravitational pull of the near satellite (moon). Land reformation also happened due to this gravitational pull, through volcanic eruptions.

This moon, as time passes by, is slowly pulling away from the earth. This is happening due to its orbit around our planet. It can be illustrated like an athlete spinning around several times while holding a heavy solid ball. He spins around until he let go of this solid ball. I’m sure you know what will happen to the ball. It will pull away from the athlete as far as it goes.

Another thing that amazed me is the functions of the moon. The moon, not only serves as light on the dark night, it serves as our shield from asteroids. If you’re going to look closer on the moon’s surface, you’ll see dozens of craters. These craters are made by asteroids that hit the moon millions of years ago. The earth supposed to be hit by these asteroids but was blocked by the moon.

Another amazing function of the moon is it gives balance to the earth’s rotation on its axis. The earth steadily rotates on its axis. The moon’s gravity provides a balance pull on the earth while rotating, thus creating a balance rotation. Without the moon, our planet will wiggle while rotating on its axis, and this will results on lots of natural disasters. An unstable rotation will give us unbalanced weather, such as extreme heat and extreme cold and storms.


On the show’s conclusion, the narrator says that we are so lucky to have the moon. However, I thought of something else to call it. I call it Intelligence and Love. It’s hard for me to believe that this scenario is a product of a random activity. God is the Supreme architect and engineer. Our solar system alone moves in order, each planet revolves around the sun without hitting one other. And our planet is the perfect habitat for man to live. The earth is neither too hot nor too cold unlike other planets. Just a little mile away from the sun, our planet would be too cold and a little mile closer to the sun, it will be too hot. We are placed perfectly in the vast of the universe.

God loves us so much that He placed a protection for us to prevent asteroids as big as cities to directly hit us. He also prepared everything on earth before He made us. The earth is already complete, with food, water, air/oxygen, animals, everything, before we came into this planet. When God made Adam and Eve, there’s nothing they could ask for more.

Let’s spend some time to meditate and appreciate the things that God has given us. Don’t forget that we already have everything that we need, even before we were born. Let’s show gratitude and give acknowledgement to God.


While many consider our moon just a far-off satellite, modern science has proved its importance again and again. In ways both recently explained and still undiscovered, it contributes to the delicate balance that human life enjoys on Earth. Read on to discover nuances of the Earth-moon relationship, as well as lunar facts and history.

If the Earth had no moon, the Earth’s surface would most likely be ravaged by hurricane-force winds, extreme temperatures, and days lasting just six hours.

• The moon’s gravity is one sixth of that of the Earth’s. It is now so small that it exerts the same upwards pull as a pea held about 20 inches above your head.

• Think the moon looks small? The moon is actually 81 million billion tons of rock and dust, more than 2,100 miles in diameter, and has mountains up to 16,000 feet.

• The moon’s widely varying temperatures range from 250º F to -380º F, or lower.

• No liquid water has ever been found on the moon’s surface.

• There are at least 135 other moons orbiting planets in our solar system; Saturn tops out the list with 46 moons.

• To date, only 12 humans have walked on the moon. Astronaut Neil Armstrong was the first, and Eugene Cernan was the last.

• Moon rocks are amazingly similar to rocks found on Earth, although they contain far less iron. This tell-tale difference provides possible evidence of the moon’s explosive origins.

• When the moon formed, it was an estimated 17,000 miles away, but has since moved away from Earth at a rate of about 1.5 inches a year.

• Absolute proof of the moon’s outward movement came in 1969, when astronauts left an 18-inch reflective plate on the moon’s surface, and scientists bounced lasers off the plate, pinpointing its distance from Earth within an inch.

• If Earth spun on a vertical axis–like planet Mercury–seasons would not exist.

• The two moons that orbit Mars are too small to stabilize its tilt, so as a result, the red planet rolls much more than Earth. Some scientists believe this is part of why there is no life there now.

• There are over three hundred thousand craters–.5 miles to over 500 miles in diameter–on the lunar surface. Most of these craters come from meteorites hitting the moon.

• The largest crater you can see from our planet is the Imbrium Basin, which is 700 miles across.
