whats the average equitorial radius of hyperion?
some websites just give 205x130x110
so im kind of confused
how am i suppose to use those numbers to find the escape velocity of hyperion?
here's a picture:

it *looks* like a captured snowball, which some people think a comet more or less is, composition-wise .... and the thin, dark layer could be just the deposit over millenia, of solar wind.
just a wild guess, but this picture sure...
