Hi, let’s check out our Solar System.
It formed together about 4.5 billion years ago.
The Solar System includes the Sun, and all the planets that orbit around it due to gravity.
There are 8 planets in the Solar System.
The four inner planets are Mercury, Venus, Earth, and Mars. They consist of rock and metal.
The four outer planets are Jupiter, Saturn, Uranus, and Neptune. They are made of gas.
For many thousands of years, humans didn’t know about the Solar System, and believed that earth was the center of the Universe.
Then Sun is 99.9 percent of the Solar Systems mass, with Jupiter and Saturn making up the majority of the rest.
Our tiny earth makes a very small percentage of the Solar Systems Mass.
Let’s check out the Sun, shall we?
Who doesn’t like the Sun?
The Sun is huge and incredibly hot.
Just think, how nice the words “Sunshine” sound? They sound very warm and comfortable to me.
The Sun is The Star that is found at the center of our Solar System.
It is 99.9 percent of the mass of the Solar System.
It is about 1.4 Million Kilometers Wide, (865 thousand miles)
You can fit 1.3 million Earths on the sun.
In my previous article, I talked about what the Universe is made of. I mentioned that the majority of the matter in the Universe is made of Hydrogen.
Matter is only 5 percent of the universe by the way.
Well, guess what?
The Sun is also made of about 75% hydrogen.
Then the other 25% is mostly helium.
The light that comes from the Sun takes about 8 minutes to be delivered to earth. It is about 150 Million Kilometers away
The sun’s surface is very hot, about 5,500 Celsius.
Right now, the temperature in my condo is 21 Celsius. If I turned the heat up maximum, it would be 32 Celsius. It would be uncomfortably hot at that temperature.
It’s like being on the beach, the temperature is ideal around 30-40 degrees Celsius.
Well the Suns surface is 5500 degrees Celsius.
Then Suns Core (the hottest part of the Solar System and the Sun) is 13,600,000 Celsius. That’s 13.6 million degrees Celsius.
If 30 degrees Celsius outside is uncomfortably hot, then I can’t imagine 13.6 million degrees.
The Sun also has a diameter of that is 110 times wider then the earth.
You can fit about 1 million planet Earths on the surface of the Sun.
OK, lets talk about Jupiter and Saturn, which are the biggest planets in our Solar System.
It is large and in charge. I has a pretty intimidating appearance as it is frequently having raging gas storms. It has many moons (about 79), and it has a bunch of rings like Saturn, except you can’t see them because they are smaller.
Jupiter is a gas giant. Big thick deadly poisonous gas surround this planet. It is the fastest spinning planet in our Solar System. It has a very strong magnetic field, about 14 times that of earth.
You could fit about 1,300 earths inside of Jupiter. That is how enormous it is.
Since Jupiter is a Gas Planet, it does not have a solid place for humans to land a spaceship on. However, humans do not believe we could fly right through Jupiter, because we do not know what is at the core of Jupiter. It could be solid.
Have you heard about that Red Spot on Jupiter? That is actually a hurricane that has been going on for 3 hundred years. It is a a ginormous hurricane that could fit about about 3 planet Earths inside of it.
Let’s Check Out Saturn.
It’s the 2nd biggest planet in the Solar System, it’s also a gas giant, made of mostly Hydrogen and Helium. It is covered with liquid gas.
764 Earths could fit inside Saturn.
It has about 62 moons rotating around it.
You know those huge rings that extend out about 240 thousand miles? They are actually made of millions of ice, dust, and rock crystals, some the size of a mansion, and others very small.
They are all are spinning around Saturn’s equator.
240 thousand miles is longer then the distance between the Earth and the Moon.
Saturn is all about storm winds raging at 800 kilometers per hour.
OK, enough about Saturn, lets show some love to Mars.
Lets Talk About Mars
Mars is pretty small, it is way smaller then earth, and the second smallest planet in the Solar System.
Mars is a red looking planet. I thought initially that this would be because it is sunburned, from being so close to the Sun.
What do you think it is?
It is actually because the rocks and soil on the surface of mars are made of iron.
You have likely seen iron before, and you know that it is not red.
However, iron that is exposed to oxygen gets rusty, which turns to what color?
Mars has water on it. OK, it is water in the form of ice. Located at it’s north pole. This picture to the left is “Curiosity” a robot explorer that humans have landed successfully on Mars, which is very cool.
Mars also has an Epic Volcano on it that is 2-3 times higher then Mount Everest. It is said to be so high, that if you were standing on top of it, you would see the planet’s curvature.
The name of the Volcano is Olympus Mons.
I have already talked about how incredible Earth is as a planet, you can read about that here.
I am going to stop there, because I am kinda getting bored, and if you are still reading this, then you may be as well.
Thanks for reading. Do you know lots about the Solar System? What do you think about the Solar System?
