This is a small planetary nebula. The magnitude 9.5 central star appears to be a binary and may have a period of 14-20 days. Its age is 10-25,000 years. Because binary novas can have more than one event where they become very bright and expel more gases, there is speculation that this might be the Star of Bethlehem heralding the birth of Christ.
