@olamundo My understanding is that we hav efewer methods to detect stars farther away from their host star. Therefore I might expect that there will be a bias in detecting fewer of them.
I am no astrophysicist though. So naturally I am not the best person to answer this.
@olamundo I will say this though. The method of detecting planets by a drop in luminosity as it transits is just one method, there are others. For example we also use variation in Doppler shift of the host star to detecting orbiting bodies.
