A galaxy is any of numerous large-scale aggregates of stars, gas, and dust that constitute the universe, containing an average of 100 billion solar masses. They are ranging in diameter from 1,500 to 300,000 light-years. this is also called "nebula". Ours galaxy is called the "milky-way" galaxy, which i might add is a very delicious candy bar if anyone hasn't tried it. It includes many stars and other planets. A galaxy is much bigger than a solar system, a galaxy includes more that just our planets and the sun.
A solar system is a "system of planets or other bodies orbiting another star", from answers.com. The Sun and the bodies moving in orbit around it. The most massive body in the solar system is the Sun. There are eight planets in our solar system. Here is a list of them from increasing average distance from the sun, Mercury, Venus, earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Every planet in our solar system revolves around the sun, each planet has its own moon or set of moons. Pluto was recently decided on as being "not a planet", it has no moons.
They are alike because they both house all of us, humans and animals. A Galaxy is far bigger than a solar system because there are many solar systems in one galaxy. I don't really have an opinion on this subject because yeah space is cool and everything, but it's way to big. There is no way that the human race will ever be able to map out or even come close to finding out what even a tenth of our galaxy is like. Yeah we can look through a telescope, but we'll never ever go anywhere. I can only hope that an alien race one day will show us a way to go to the ends of the universe.

Good content of information. You keep the facts, straight and simple. Just the way I like them, and I do agree that it will be impossible to map out the universe, due to the fact that it is so extensive.
Beautiful Job!
Fabulously yours,
Megan
Great Job Cam! That was really good. Very good information with your touch. Thanks for changing your colors so that I could read it. I hope that aliens come to save us too.

Great Job. Great information also. Facts were easy and simple to follow. I also agree with Megan about mapping everything out will be impossible. But great info
the one and only

Cam your font color is still hard to read, it kind of gives me a headache. Good post even though I didn't want to read it. Nice to see you got some "answers".
Maybe one day ET can show us the way but right now he is all high and mighty in Hollywood. "Can't help you now...I'm movie star" says ET.
Nice Job
