Adaptive optics , large primary mirrors , and careful selection of target stars are the keys to ground-based imaging of extrasolar planets .
Our near-IR survey is capable of identifying exoplanets of 1-10 M { { } _ { J } } within 100 AU of young ( t < 60 Myr ) , nearby ( d < 60 pc ) stars .
For very young and proximate targets such as GJ 803 ( 12 Myr , 10 pc ) we are able to detect exoplanets with parameters approaching those of planets our solar system ( 1 M { { } _ { J } } at 19 AU , 2 M { { } _ { J } } at 9 AU ; 5 M { { } _ { J } } at 5 AU ) .
We have thus far imaged over 100 stars with Keck AO .
Here we report on our progress , discuss specific observing strategies , and present detailed sensitivity limits .
