1000 MILLION PLANETS

Astronomers and planet hunters have thus far identified less than 10000 extrasolar planets...but they will probably need to identify 1000 million planets before they discover another one with life...how long will it take to identify 1000 million planets....it could take more than 1000 years with our technology...a habitable planet may be 1 in 1 billion or even far less likely than that...and there may only be less than a million planets within our observational limits from Earth...the odds are too great but we plow ahead.
