What's this?

Pretty sure transit is currently the best method for earth sized planets

Wobble depends on doppler shifts that require massive planets often reall close to the star to exert enough influence on the star to be measured, whereas transit light curves can tell size, period, and when combined with spectroscopy, components of the planets artmosphere.
