That's a crapload of habitable planets. In fact, I
think it's
also the number of Population One stars in the galaxy....

So far we've only discovered one habitable planet. What's the
estimate based on?

At a guess, the fact that the only solar system we have complete data
on - our own - has roughly 10% habitable planets.

Recently changed from 11.1% to 12.5%, so the trend is up.
