Stars

Heliocentric solar system By: RuM

Summary: If one were to look up into the night sky, they would notice something, the stars. In the vastness of space, there are these big balls of fire that shine so brightly you can be can see them from trillions of miles away. The thing is these stars are doing something that most people wouldn't imagine when thinking about stars. That thing is nuclear fusion, this is when stars use a little bit of energy to fuse 4 hydrogen atoms, into one helium atom. This is why stars shine, because of all the energy being used to do this over and over again.

SP2: Developing and using models
Due to the fact that space is so big, we had to rely on models quite a bit to help us understand the importance of various things in space, such as stars. We made a small model of the solar system that was about 5 feet in length, which is much shorter than the millions of miles that our solar system covers. We used the paper to gauge the relative distance of all of the planets to each other, including the Sun and the Kuiper belt, which were both at the edge of the solar system.

XCC: Scale, Proportion, and Quantity

When talking about space, one has to acknowledge how vast it really is, the Earth may seem to be a big place for some, but just looking at our solar system, one can see how Earth is really just a speck in the entirety of space. The sun is one million times larger than the Earth, and it is no where near the biggest star in the galaxy. It takes light, the thing that can almost travel instantly 4 years to get to the nearest star to our solar system.
