Their existence can be confirmed through techniques such as astrometry, radial velocity, and pulsar timing.
Their existence can be confirmed through techniques such as astrometry, radial velocity, and pulsar timing. The Kepler mission seeks to find one variety of these, which are defined as objects with true masses below the limiting mass for the thermonuclear fusion of deuterium. The discovery of Eris forced a  redefinition of these celestial bodies, and satellites orbiting them will eventually break apart if they are within the Roche limit. FTP, what is this group of objects to which Pluto no longer belongs.
