Are you ready?
The Solar System
The Solar system is the moon, the stars, the planets, and everything else connected to it with gravity.
The outer spiral of the Solar System is known as The Milky Way.
In our Solar System, you will also find dwarf planets, such as Pluto, as well as Moons, Meteoroids, Asteroids, Comets
Our Solar System also consists of The Kuiper Belt and the Oort Cloud.
Meteorites- Space Rocks
Comets- Frozen Gas, dust, and rock in a snowball type shape.
Asteroids- Early formation leftovers that are airless and rocky.
The Kuiper Belt
The Kuiper belt lies beyond Neptunes Orbit.
It is one of the largest structures in our Solar System.
Its shape is similar to a donut.
Comets are from the Kuiper belt.
It is found very far out in Space.
In 1983, NASA's Pioneer 10 spacecraft entered the Kuiper Belt when it crossed into the outer space beyond Neptune, during that time Pluto had been discovered.
The Oort Cloud
A giant Spherical Shell that surrounds the Solar System.
The Oort Cloud is found beyond the fringes of the Kuiper Belt.
It has a thick wall made up of icy debris from Space. This debris is huge and is usually the size of mountains or bigger.
Known as the heart of the Solar System.
A magnetic field is formed from electric currents which carried through by solar wind.
The Sun's gravity holds the Solar System together, ensuring it keeps everything in its orbit.
Earth and the Sun create connections and interactions that create the:
It is a hot gas ball.
The Sun is a yellow dwarf star.
Mars is the 4th planet from the Sun.
Mars has 2 known Moons.
It is a very cold and dusty planet.
Mars has weather, seasons, and ice caps.
On Mars, you'll also find canyons and volcanoes that are extinct.
It is the most explored planet.
The length of a year is 687 Earth days.
Mars is 141.6 Million Km's from Earth.
Closest to the Sun.
Mercury is ringless.
It has no Moons.
Mercury's day temperature can reach up to 430 Degrees Celcius, and the temperature during the night can drop to -180 Degrees Celcius
Mercury is a very rocky planet.
The length of a year is 88 Earth days.
Mercury is 66.4 Million Km's from Earth.
The 2nd planet from the sun.
The size and structure of Venus is similar to Earth.
Venus spins in the opposite direction to the other planets. It is the hottest planet due to its thick atmosphere
It is a ringless planet.
Venus's clouds are known as chasing clouds, this is due to the hurricane type winds that occur on the planet.
A spacecraft, Akatsuki, is currently orbiting around Venus (2020).
The length of a year is 225 Earth days.
Venus is 180.6 Million Km's from Earth.
3rd planet from the Sun.
Earth is the only planet with liquid on its surface.
It is the only planet with living things on it.
Earth has 365 days & 366 days during a leap year.
Each day has 24 hours in it.
It takes a year for Earth to orbit around the sun.
It is a ringless planet.
Earth has a "protective layer" called the Atmosphere, this helps protect the Earth from getting hit with big meteoroids, before the meteoroid hits the Earth the atmosphere breaks them down into small particles.
Earth has one moon.
5th planet from the Sun.
Jupiter is the largest planet in the Solar System.
It is almost twice as big as all the other planets combined.
Jupiter is known for its "stripes", these "stripes" are cold clouds made up of Ammonia and water which float in an atmosphere of hydrogen and helium.
Jupiter has 79 known Moons.
On Jupiter is known for its Great Red Spot, this is caused by a giant storm that has been active for hundreds of years.
The length of a year is 4,333 Earth days.
Jupiter is 773.07 Million Km's from Earth.
6th planet from the Sun.
Saturn has 82 known Moons.
Saturn has a ring around it which consists of 7 rings which have many gaps between them and, is made up of rock and ice.
It is made up of Hydrogen and Helium and is considered a gas giant.
The length of a year is a +- 10.7 hour Earth day.
Saturn is 1,4 Billion Km's from Earth.
8th planet from the Sun.
It is a dark and cold planet.
It is an ice giant that experiences extreme winds.
Neptune is not visible to the naked eye.
Neptune has 14 known Moons.
In 1989 NASA's spacecraft, Voyager 2, passed Neptune on its way to explore the Solar System.
The length it takes Neptune to orbit the Sun is, 165 Earth years.
Neptune is 4.5 Billion Km's from Earth.
7th planet from the Sun.
Uranus was discovered in 1781 by astronomer, William Herschel, it was first mistaken for a star and later became a planet.
Uranus is bigger than Earth.
Uranus is known as the ice giant.
It has 13 known rings.
Uranus has 27 known moons.
The length it takes Uranus to orbit the Sun is, 84 Earth years.
Uranus is 2.9 Billion Km's from Earth.
In our Solar System we Dwarf planets, a dwarf planet is a mass that does not contain any satellites or dominate any areas in space.
It has a direct orbit around the sun.
Some of the known Dwarf planets are:
There are however many other undiscovered Dwarf planets in the Solar System.
5th largest satellite in the Solar System.
The Moon orbits Earth and is Earth's only satellite.
The Moon has a dark surface.
The first man to walk on the Moon was Neil Armstrong, in July 1969.
Stars are gas balls that contain Hydrogen and Helium.
Stars light up the sky due to the nuclear forges that happen in the center of the ball.
The Sun lights up the sky in the day and the stars light up our skies at night.
Hundreds of years ago the ancient explorers used the stars to navigate their way.
Now stars are used to navigate the universe.
Stars have a lifespan of billions of years.

I hope you enjoyed learning about The Solar System just as much as I did.
Lots of love,
