=Earth= The Earth is the third planet from the Sun. It is one of the four terrestrial planets in our Solar System. This means most of its mass is solid. The other three are Mercury, Mars, and Venus. The Earth is also called the Blue Planet, Planet Earth, and Terra.

The Earth is home to millions of species of plants and animals, including humans.

Earth is the only planet in the galaxy which is known to support life. Earth has many places that are suitable for humans to live; although, some areas of the planet can be uninhabitable, i.e, Volcanoes.

Science shows that Earth formed around 4.5 billion years ago. The organisms that live on Earth have caused Earth to mutate its atmosphere; this is called biosphere. 71% of Earth's surface is covered in saltwater oceans. Earth is the only place in the Solar System where liquid water is known to exist(currently). The other 29% is made of rocky land in the shape of continents and islands. Earth interacts with other objects in the Solar System, particularly the Sun and the Moon. The Earth orbits the Sun roughly once every 365.25 or 365 and 1/4 day(s). One rotation of The Earth is called a day and one orbit around the Sun is called a year. This is why there are roughly 365 days in a year, with a leap day added to the calendar due to the Earth taking 1/4 of an extra day(1/4 of the extra day accumulates to form a full new day in 4 years) in a year. The year in which the Earth has an extra leap day is called a Leap Year, which is always a multiple of 4.
