摘要

The nearby star Gliese 229 harbours a 'brown dwarf' companion: an object less massive than a star but more massive than a planet. High-resolution observations reveal that it is two objects, each about 30 times the mass of Jupiter, that circle one another every 12 days as they orbit their sun every few hundred years.
