g STARS - More than half of the stars in our galaxy have a stellar companion. And yet, of the 130 or so currently known exoplanets (none of which are Earth-like), only about 20 of them are around so-called binaries. The percentage may grow higher. The current ratio is affected by an observational bias: planet hunters tend to avoid binaries because the star-star interactions can hide the planet signatures. See article. Note: This article is from 2005.
