Comment on Size Comparison: Pluto and Australia

  Do you mean the Trojans? They’re excluded from the mass calculation of ‘clearing the neighbourhood’ because they’re in a resonant orbit - their orbit is a consequence of Jupiter’s mass.

    I don’t know. I don’t think we should make excuses for Jupiter just because of its size. Pluto’s doing the best it can. Could any of us do any better, so far out from the sun?

      Jupiter does throw its weight around a bit too much.

        Thanks to your comments, I went looking at more about Jupiter’s influence on us and read that most of the other planets are more in line with Jupiter’s orbital plane than the Sun’s equatorial plane (which sounds impressive, but maybe only makes complete sense since the planets would have all initially formed from the same disk). Anyway, thanks

        No kidding. The Sun - Jupiter barycentre is outside the Sun.

      Jupiter was declared too big to fail.
