It flew in a circle, as Pas/Typhon intended.

The life forms of Blue are edible to those of Urth, and vica-versa.   On a
galactic scale this is 99.99 percent smilarity.

It is not possible that the Blue/Green system could be gravitationally
stable.   Ergo, it is recent.

Both argue  for a low gravity.
