Abstract: Observations of a wide-separation quadruple system in the Perseus star-forming region reveal a young protostar and three gravitationally bound dense gas condensations; each condensation is expected to form a star and the closest pair will form a bound binary, while the quadruple stellar system itself is bound but unstable on timescales of 500,000 years.
