Our Earth is the only planet known to be inhabited by living things. This planet is very beautiful and is one in a trillion. Today I will tell you all about our lovely planet and things you probably never knew.
Earth is the 3rd planet from the Sun. It’s just a little bigger than our neighboring planet Venus. Earth is the largest planet out of the first four planets that are made of rock and metal called terrestrial planets.
The name “Earth” is a thousand years old, and it is derived from the German word for “the ground”. All the other planets got their names from Greek and Roman gods.
Earth has a radius of 3,959 miles (6,371 kilometers). It is the biggest planet out of all the terrestrial planets and is the fifth-biggest planet overall. Astronomers measure the distance between objects in the solar system using Astronomical Units (AU). One AU is the distance between Earth and the Sun.
The Earth takes 23.9 hours to finish one rotation and 365.25 days to finish a revolution.
The Earth's axis is tilted 23.4 degrees, and this is the reason why seasons occur on our planet.
Earth is made up of four main layers: (in order from the innermost to the outermost layer) the inner core, the outer core, the mantle, and the crust.
Our Earth is truly one in a trillion, and planets with the same conditions as Earth are hard to find. So, we should start respecting it and try to keep it as clean as possible. We humans have done nothing but harm this planet, so let's make a change now before it is too late. This is the only planet we have. Start taking action, and encourage others to take action too.
