Our solar neighborhood is an exciting place. The Solar System is full of planets, moons, asteroids, comets, minor planets, and many other exciting objects. Scientists believe that the Solar System evolved from a giant cloud of dust and gas. They believe that this dust and gas began to collapse under the weight of its own gravity. At the center of this spinning cloud, a small star begin to form. This star grew larger and larger, as it collected more of the dust and gas that were collapsing into it. Further away from the star that was forming in the center were smaller clumps of dust and gas that were also collapsing. The star in the center eventually ignited forming our Sun, while the smaller clumps became the planets, minor planets, moons, comets, and asteroids.
Galaxies on the other hand are large systems of stars and interstellar matter. There are many different types of galaxies such as the spiral, lenticular, elliptical, and irregular. We live in a spiral galaxy known as the Milky Way. (well at least you should know that) Galaxies emit light of every wavelength and were known as the Island Universes. Our own galaxy has over 200 billion stars and also has a disk in it, which holds our solar system. Galaxies are much bigger than solar systems and contain billions of extra stuff.
I think space is a very fascinating thing. I love stars and I am actually a proud owner of a star that is on ursa minor. I received it as a gift which I thought was pretty cool. Although I will never get to see an entire galaxy in real life, it would be really cool to see another planet in our Solar System like Jupiter perhaps;)

Good Job! you have some very good points about galaxies and solar systems. i agree with what you said about galaxies. there is so many things in our universe that we will never be able to see or experience or touch. its scary to think that we're not the only ones our there!!!
that's sweet! i wish i owned a star! I liked the quote at the end. But good job on your post i really this is all pretty interesting too.

Keri,
I reaally liked the information that you included. How did you become the proud owner of a star? That's so cool!!!!! I also liked the quore at the end of the blog. It really personifies the blog.

Great job in giving us a feeling of the differences of solar systems and galaxies. Maybe next time put a space between paragraphs so they're easier to read and know where one ends and another begins. I think it's so cool that you own a star, I'm jealous.
Nice post this week. You included great info in it. Excellent quote at the end.
