Which method is ideally suited for detecting planets in orbits oriented nearly face-on to Earth?

Answer

Astrometry

Astrometry thrives on measuring the sideways displacement of a star, which is maximized when the orbital plane is nearly face-on; in contrast, Radial Velocity requires an edge-on orientation.
