Despite extensive Doppler searches, no companions of Jupiter, or Brown Dwarf, mass have been found within a few AU of more than 100 late-type stars and, for many, astrometry suggests that there are none in larger orbits either. Terrestrial-mass companions have been found for the millisecond pulsar PSR1257+12. I also consider what improvements in optical spectroscopic techniques would allow us to detect stellar companions of Uranus-mass.
