The most incredible fact about the Earth is that it is the only known planet in our solar system that is capable of supporting life.
The Earth is estimated to be around 4.54 billion years old.
The circumference of the Earth is approximately 24,901 miles (40,075 kilometers) at the equator.
The Earth's seasons are caused by its axial tilt, which is tilted at an angle of 23.5 degrees relative to its orbit around the sun.
It is estimated that there are around 8.7 million species of plants and animals on Earth, but the exact number is still unknown.
