The solar system is full of many objects, some known and some are unknown. Of the known, there are the planets, the stars, and the moons that make up the galaxies, each of them unique in their way. However, there lingers a question that has never been fully answered by the many scientists that study the solar system. Is the moon a planet or a star?
Is the Moon a Planet?
To tell whether the moon is planet one will need first to know what makes a planet. The International Astronomical Union created a set of three requirements that an object in the solar system has to have for it to be considered a planet. First, it must be in orbit around a sun, secondly it must have sufficient mass to assume a near round shape called the hydrostatic equilibrium, and lastly, it has to have cleared any obstacles from its path in orbit. These three requirements disqualify the moon from being referred to as a planet as it does not orbit any sun.
Is the Moon a Planet or a Star?
The moon is neither a planet nor a star. Instead, it is a satellite. The moon was formed billions of years ago from debris.
Is the Moon a Star?
A star in the solar system is a force. Stars are bigger than planets or anything else in the universe and they are not made of solid material like planets. An example of a star is the sun which the earth revolves around in orbit. The sun is 109 times bigger than the earth. It is made up of hot gases that emit a lot of energy in the form of heat and light. All these are properties that the moon does not possess. The moon, on the other hand, is solid and very small in size and does not have anything orbiting around it. Therefore the moon cannot be classified as a star. This, therefore, begs the question, what exactly is the moon?
The Moon Is a Satellite Object
Earth’s moon is believed to have been formed billions of years ago from the debris that resulted in the collision between the earth and another planet-like body. As a result, this makes the moon more of a planet than a star because it is made up of the same materials that make up the earth, the only drawback for the moon, however, is that it is too small to the extent that it is bound to earth’s gravity. Besides, it does not have the size or the gravitational force of a planet, and therefore, the moon is simply a satellite object that is neither a star nor a planet. As far as the composition of the moon goes, it is made up mostly of an iron-rich core, a fluid outer core made of liquid iron that is covered by solid mantle and crust. The surface of the moon is made up of silica, alumina, lime, magnesia, titanium, and sodium oxide, and all this are minerals that are present on earth which adds credibility to the collision theory. The moon has a diameter of 2,160 miles with a surface area of 14,658,000 square miles, and it will require 81 moons for them to fit into the earth.
