- Earth is the third planet from the sun in our solar system. Its name comes from the the old English and Germanic words meaning ‘the ground’.
- Our amazing planet has been around for quite some time. By researching our planet’s rocks, scientists have calculated the Earth to be around 4.5 billion years old!
- Like all the planets, Earth orbits (travels around) around the sun. And it does so at some serious speed –– around 30 kilometres per second, in fact!
- Have you ever wondered why we have different seasons? We’ll tell you –– it’s because the Earth is tilted 23.4 degrees on its ‘axis’, an imaginary line straight through the middle of the planet form the North Pole to the South Pole.
- It Is The only Planet We Have Found That Contains Life.
- Earth’s Surface Is Mainly Water.
- Earth Rotates at Around 1000 Miles An hour.
- Earth’s Atmosphere Is Made of Gases.
- Earth Isn’T Perfectly Round.
- Days on Earth Are Getting longer.
- Earth Used to Look Very different.
- You Could Fit A Million Earths in The Sun.
Scientists have looked all around our solar system, as well as other solar systems, to see if any planets host life like the plants and animals on ours. So far Earth is the only planet that seems to have life.
About 71 percentof the Earth’s surface is water-covered, and the oceans hold about 96.5 percent of all Earth’s water.
We don’t feel the Earth itself spinning because we are held close to the Earth’s surface by gravity – that’s probably good because we would feel very dizzy moving that fast!
The mixture of gases, what we often refer to as ‘air’, are nitrogen, oxygen, argon, and carbon dioxide. Without them, we couldn’t live.
Earth may look round but it’s actually not perfectly round. The planet bulges around the equator by an extra 0.3 percent due to how it rotates about its axis.
The length of Earth’s day is increasing. When Earth was formed 4.6 billion years ago, its day would have been roughly six hours long. By 620 million years ago a day was around 22 hours. Today, the average day is 24 hours long, but is increasing by about 1.7 milliseconds every century. The reason? The moon is slowing down Earth’s rotation through th...
Over the 4.6 million years Earth has been around it hasn’t always looked the way it does now. At its beginning, Earth was extremely hot, and full of molten magma. Over the course of a few hundred million years, the planet began to cool and oceans of liquid water formed. About 250 million years ago, the continents came together to form a supercontin...

Oct 11, 2024 · Structure and Surface. Earth is a terrestrial planet. It is small and rocky. Earth's atmosphere is the right thickness to keep the planet warm so living things like us can be there. It’s the only planet in our solar system we know of that supports life. It is mostly nitrogen, and it has plenty of oxygen for us to breathe.
- Namesake. The name Earth is at least 1,000 years old. All of the planets, except for Earth, were named after Greek and Roman gods and goddesses. However, the name Earth is a Germanic word, which simply means “the ground.”
- Potential for Life. Earth has a very hospitable temperature and mix of chemicals that have made life abundant here. Most notably, Earth is unique in that most of our planet is covered in liquid water, since the temperature allows liquid water to exist for extended periods of time.
- Size and Distance. With an equatorial diameter of 7926 miles (12,760 kilometers), Earth is the biggest of the terrestrial planets and the fifth largest planet in our solar system.
- Orbit and Rotation. As Earth orbits the Sun, it completes one rotation every 23.9 hours. It takes 365.25 days to complete one trip around the Sun. That extra quarter of a day presents a challenge to our calendar system, which counts one year as 365 days.
Jan 25, 2023 · The Earth is a Unique Planet as it is the only planet that supports life in the solar system. Earth is also called a blue planet or water planet.
