=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 best and coolest planet in the whole galaxy. Earth is a place that's perfect for humans to live. Science shows that the Earth was formed about 4.5 billion years ago. The organisms that live on Earth have completely changed their air (atmosphere); this is called the biosphere. 71% of the Earth's surface is covered by salt water oceans. Earth is the only place in the Solar System where liquid water is known to exist today. The other 29% are formed by rocky terrains in the shape of continents and islands. The Earth interacts with other objects in the Solar System, particularly the Sun and the Moon. The Earth orbits the Sun approximately once every 365.25 days. A rotation is called a day and an orbit around the sun is called a year. That's why there are 365 days in a year, but a leap day added to the calendar once every 4 years.

Earth is the only place in the Solar System where liquid water is known to exist at present. The other 29% is made of rocky land in the shape of continents and islands.

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.
