Hike into main area of the Lower Satellites by following the signs to the Third Flatiron. When you get to the A-7 Boulder, go around to the east side toward the V8 Face Full of Brian. From Face Full of Brian, go 15 yards east into the talus to an alley that runs east-west between a few boulders. From there, drop around to the north to the base of a tall north-facing slab which is on the opposite side of the boulder from Reach for the Stars.
North Star is the right hand side of the north face near the arete. It has plenty of good holds, gets a little balancy in the middle. Several edges are available for the finishing moves up to the top. Probably easier than V0, but being more than 15 feet above talus and a trip to the hospital makes it seem a little harder.
