the radial velocity method's zone of discovery is vast, as distant exoplanets too dim to be observed are detected by
B
the radial velocity method, with its vast zone of discovery, detects exoplanets that are too dim to be observed by
C
distant exoplanets too dim to be observed are detected within the radial velocity method's vast zone of discovery through
