    The closer they are to their star, the easier their effects on the star can be seen by us. Many of the exo-planets found are closer to their star than Mercury's orbit which is why we believe them to be tidally locked. As they are orbiting Red Dwarf stars they aren't quite as hot as we would normally expect a planet in such a close orbit to be.

    (D)

    The detection method for the first hundreds of extrasolar planets

    was mainly the radial-velocity method,

    which favors the discovery of planets with small orbits.

    So one expects that future discoveries by other means may include many more

    planets with larger orbits.
