How does the way in which the solar system formed explain the orbits, sizes, and compositions of the planets?

1. Star - a massive ball of gas in outer space that gives off heat, light and other forms of radiation
2. Sun - any star around which planets revolve
3. Solar system- a system of objects that revolve around a star

Today is the first day of Quarter 3.  I will upload my grades for Quarter 2 by Wednesday.  If you have anything to turn in for Quarter 2, tomorrow is the final day to take late assignments or any extra credit!  Please see if you have anything missing or if you are on the border and extra credit would help to raise your grade.  You are in control of the grade you get based on the effort that you put in!

1. System- a group of related objects that work together to form a function
2. Orbit- the circular path of an object as it revolves around another object
3. Theory- a set of statements or principles devised to explain a group of facts or phenomena
4. Nebular theory- About 4.6 billion years ago, an unknown event caused the gas and dust to start to collapse under its own gravity and the giant gas cloud began to contract.
5. Accretion – “growth” the coming together and cohesion of matter under the influence of gravitation to form larger bodies.
