3·This open cluster is particularly ancient, estimated to be nearly one billion years old.

4·NGC 2818 is one of very few planetary nebulae in our galaxy located within an open cluster.

NGC2818是银河系中少数几个位于疏散星团内部的行星状星云之一。

5·It is called an open cluster because its stars are loosely bound and have started to spread out.

它被称为疏散星团，因为它的成员恒星结构松散而且还有恒星在扩散离开星团。

6·The star is part of the open cluster of stars labelled NGC 2264 and known as the Snowflake cluster.
