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 dangerous for humans or uninhabitable.
Earth formed around 4.5 billion years ago. The organisms that live on Earth have changed its air (atmosphere), which is part of the biosphere. 71% of Earth's surface is covered in salt water oceans. Earth is the only planet in the Solar System where liquid water is known to exist at present, however liquid water is present on a number of moons including Europa and Enceladus, where geysers of water have been observed by NASA spacecraft. 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 days. One spin is called a day and one orbit around the Sun is called a year. This is why there are 365 days in a year, but a leap day added to the calendar once every 4 years.
Got stuck in a loop again, nearly had to start over. This is actually rather frustrating, it must scare away people who are brand new.
Science shows that Earth formed around 4.5 billion years ago. The organisms that live on Earth have completely changed its air (atmosphere); this is called a biosphere. 71% of Earth's surface is covered in salt water oceans.
