You might want to go on NASA.gov. I can't think of many right now. I have them bookmarked, but I'm on a school computer.
Yes, on a Saturday.
Yes, for Science Olympiad.

Back to notesheet fonts, you might want to use Arial Narrow. I kind of just rushed through my notesheet for Invitationals, I'll have to work more on it, but I'm using size 8 right now.

Oh, and don't forget diagrams~ Just make them as small as possible. c:

Do we or do we not have to know anything about constellations this year? Thats my question.

You do not need to know about constellations. The only thing they could ask you is what constellations the planets appear in at the time of the competition. The overwhelming majority of Solar System, however, is the Solar System.

Actually, that bit's been taken out of the rules, so now you don't need to know a single thing about constellations.

### Re: Solar System B

At my regional there was a question that said-How do you calculate the orbital period of a planet with only AU given? Is there a formula for that or do you just have to know it?

Yeah you would use Kepler's third law of planetary motion- the square of a planet's orbital time is proportional to the cube of it's semi-major axis, or $\frac{P_1^2}{P_2^2} = \frac{R_1^3}{R_2^3}$
