Large And Close

"Hiding Place," see here.

Assessing one of the species in the zoo ship, Torrance concludes:

"'I imagine their world, though of nearly Jovian mass, is so close to its sun that that the hydrogen was boiled off, leaving a clear field for evolution similar to Earth's.'" (p. 596)

Generalizing from the single instance of the Solar System, theoreticians had thought that a planetary system would have terrestroid planets near the sun and gas giants further out whereas more recently detected exoplanets include Jovoids in close orbits as in this speculation by Anderson/Torrance.

Very reasonable guess for the time; it just happened not to be correct, with the exception of hypothetical "chthonic planets": https://en.wikipedia.org/wiki/Hot_Jupiter

(This invalidate John Babnes' t"Thousand Cultures" planets, too.)

Kaor, Paul!

Now that was interesting, that Anderson thought of the possibility there being "hot Jupiters" long before they were discovered for real.
