Planet Earth is the third closest planet to the sun in the solar system, it rotates on an axis and revolves around the sun. The moon is the Earth’s natural satellite that is only visible at night and obtains its light from rays from the sun. It is the fifth largest satellite in our solar system and the largest satellite relative to the size of the planet it orbits.
The moon has 8 phases they are: “new moon”, then the “waxing crescent”, after which the “first quarter” comes out, after some days the “waxing gibbous”, the “full moon”, the “waning gibbous”, the “third quarter” and the “waning crescent”; then the cycle starts back from the origin. Many planets in the solar system have more than a single moon like: Mars with 2 moons, Jupiter has 67, Saturn 62, Uranus 27 and Neptune 14.
The Earth has just a single moon, but some years ago a Universal body called a “Quasi-satellite” was found orbiting the sun and seen here on Earth as a second moon. These satellites are objects orbiting the sun, just as the Earth is. The only difference between them is that the shape of the Quasi-satellite is slightly different from that of Earth.
In space, the most common of this type of satellite in recent time orbiting the sun which might have been called a “second moon” for the Earth is called “3753 Cruithne”. This Universal body is nothing but an asteroid about 5 kilometers (3miles) wide; It is one of the thousands of asteroid whose orbits cross Earth’s orbit. The moon contains rocks and metals like; iron and titanium oxide, just like; Earth, Mercury, Venus and Mars. Our moon’s surface is similar to that of Earth’s, only different in the soil color and texture with a depth of 3 and 20 metres.
People on Earth know that it has only one moon, but there have been some discoveries that have shown us that there exist smaller (mini-moons) in space. These mini-moons are just asteroids that orbit our planet, and they don’t follow a smooth path, but seem to dangle around our world. From calculations of astronomers, most of these objects are no larger than 3 feet across. About once every 50 years, there’s one like the size of a garbage truck and once every 100 thousand years there’s one about the size of a football field orbiting the Earth that’s big enough to be seen with or naked eyes.
Maybe billions of years ago the Earth had more than one moon, or maybe some time in the future it may have two moons, right now it has just one moon. Our moon is thought to come from the after effects of a collision between our planet and an object the size of Mars called “Theia”. This is thought to have happened millions of years after the birth of Earth. Since then, no other moon was seen or stayed in our world’s orbit for a period of time.
Many so-called moons in our solar system were just asteroids trapped by the gravity of other Universal bodies like ours. The solar system contains many beautiful terrestrial bodies and our moon is part of them. A lot of journeys and research were made on the moon and mankind have gathered information about it. Some of us may want to have more than one moon, for now, no other moon has surfaced like the current one we see all over the world so it remains one.
