The object classified as a Class 0 protostar is VLA 1623. VLA 1623 is an exemplar Class 0 protostar, representing a type of embedded protostar that has yet to accrete the majority of its mass. It was discovered in 1993 and is possibly younger than 10,000 years old. Class 0 protostars are in the early stages of star formation and are characterized by their embedded nature and ongoing accretion processes as they gather mass from surrounding material.
