Facts about our Solar System

In 2006 Pluto was downgraded but now there are four dwarf planets in the solar system.

I was really shocked when I found out that our sun wasn’t that big and that there are other stars which are much bigger than the sun. Some people call the sun the star. That’s why in lots of sayings people and many scientists say that the sun is the closest star to earth. The sun’s surface is called the photosphere. The temperature of the photosphere is about 10,000 Fahrenheit. Did you know that the sun is made out of 92% hydrogen, 7% helium and the rest is other low number gasses.

The moon does not give off light of its own. It is the sun that gives light to the moon. The moon reflects the suns light.

Falealupo in Samoa is the last place in the whole world to see the sunset which I think is pretty cool.

Other interesting facts:
Pluto is about the same age as the Sun which is about 4.5 billion years old.
The clouds of Venus is filled with sulfuric acid.
Venus has mountains that are higher than Earth.One of the mountains names are Maat Mons which is more than 5 miles high.
Scientists have found out that Venus is the brightest planet viewed from Earth.The reason why they know this is because the planet rotates from East to West. The only other planet that does this is Uranus.
