An Earth - like planet would cause a bigger wobble and a darker transit in a red dwarf than in a sun, and the effect would be even more pronounced if the planet were in the habitable zone — because the habitable zone, where liquid water can exist, lies closer to a cool red dwarf.

Kepler, which will keep a continuous watch on a patch of stars for more than three years, is better suited to finding planets like our own in terms of orbital periods as well as other parameters, although it will likely be a few years before it moves from the hot objects it has already discovered to cooler, potentially habitable worlds, whose transits are subtler and less frequent.
