That's pretty much it.
Is it perfectly spherical, or is it squashed like the Earth due to a rotation?
Is it rotating through an axis perpendicular to the plane of the solar system?
If yes, can we measure this using Doppler shift of spectral lines either side of the sun, or something like this?
Not homework, just something I randomly thought of. It seems that it has to have at least some sort of angular momentum, what are the chances all the cold gas that collapsed to form it had exactly zero net angular momentum, right?
Thanks,
Mike
