NGC 1333-IRAS 4B

from Wikipedia, the free encyclopedia

NGC 1333-IRAS 4B or short- IRAS 4B are protostars in the constellation Perseus and are in the fog NGC 1333 . The stars are approximately 235 parsecs apart , but that is not entirely certain. There is a dust disk of 0.24 solar masses and an envelope with 2.9 solar masses. Since NGC 1333-IRAS 4A is only 7500 AU away, the two systems are combined as the NGC 1333-IRAS 4 region.
