Visiting Earth
By: Makayla Thornhill
What is Earth?
Earth is the third planet closest to the sun of the Milky Way Galaxy. It is the only planet - that we know of- that has the perfect conditions to sustain animal, plant, and human life. Here on Earth, you can enjoy the pleasures of:
- Fresh water
- Four different distinct seasons
- Perfect living conditions
- Lovely temperatures averaging about 61 degrees Fahrenheit - varies all over Earth.
- Different environments from sandy beaches to snowcapped mountains
- Our gravitational pull - no more floating around in space!
- Breathable air
- Animals, reptiles, amphibians, marine animals, plants, and humans!
- And much more…
We can’t wait to see you here on Earth; you absolutely love it here. We are very friendly and our environments and ecosystems are very interesting and fun!
What is Earth's History/Facts?
Earth has a very interesting history, starting 4.54 billion years ago, when Earth and other planets started to form, and it just happened that Earth was being created the perfect distance from the Sun for it to be able to have an atmosphere, liquid oceans, and a perfect magnetic pull (gravity). The first life on Earth was a species of single celled organisms that lived in Earth’s oceans. One big early group of species found was dinosaurs. Dinosaurs were unfortunately spontaneously wiped out by some force that is still unknown. After that, animals, plants, and other objects started to appear and objects evolved into different things and time went on. Eventually we get to now, where humans rule the world, but still respect the other inhabitants our beautiful Earth.
Some amazing facts include:
- Earth has one moon
- Tilts roughly at 66 degrees
- 70% covered in water
- Only planet in our solar system that isn't named after a Greek or Roman mythological god/goddess
- Earth was once considered the center of the universe
- Earth's rotation is gradually slowing
- Earth has the greatest density out of all the planets in our galaxy
- Earth's water was originally trapped underground
- Each day is one rotation of Earth on its axis. Earth rotates itself completely on its axis in 24 hours. This is called a rotation and a day
- While Earth is rotating, it is also revolving around the Sun. It takes 365.25 days for Earth to go around the Sun completely. This is called a year and a revolution.
Number Facts:
- The Earth's mass is 5,972,190,000,000,000 billion kg
- Earth's equatorial diameter is: 12,756 km
- Earth's polar diameter is: 12,714 km
- Earth's equatorial circumference is: 40,030 km
The Science of Earth and Our Solar System
Our energy comes from nuclear fusion. Nuclear fusion is what occurs when two atoms of hydrogen combine to form a helium atom, energy is produced. This nuclear fusion is also what makes stars shine.
All the objects in our solar system are spherical because they all have sufficient enough masses that their self- gravity's overcome rigid body forms so that it can assume a hydro-static equilibrium (almost round) shape.
Lastly, a light year is the time it takes light to travel in one year, which is 186,000 miles per second.
