### Re: Solar System B

my only question is how do you determine the major axis if you only have the aphelion?

*sorry aphelion

perihillion = at sun
aphelion = 50,000AU
Therefore, the major axis is 50,000 AU
Refer to my picture.

### Re: Solar System B

wow i am stupid....
haha i saw the sun was the perihelion but I was like "how is that possible" so i disregarded that part
oh well, yeah you're right, but they pretty much gave you a major axis, just the question was worded weirdly.

There are a few practice tests in the test exchange in the Wiki. However, people haven't been posting any, so there's only two there right now, but check back often.
