The Butterfly Cluster (cataloged as Messier 6 or M6, and as NGC 6405) is an open cluster of stars in the southern constellation of Scorpius. Its name derives from the resemblance of its shape to a butterfly .

2015年2月11日 · Messier 6, also known as the Butterfly Cluster or NGC 6405, is a bright open cluster located in Scorpius constellation.

Butterfly Cluster is an Open Star Cluster located in the constellation of Scorpius in the southern hemisphere. Butterfly Cluster's distance from Earth is 1,600.00 light years. Butterfly Cluster is also known as M6 or Messier 6 when Charles Messier catalogued it in 18th - 19th Century France.

疏散星 团m6，又称为ngc 6405，外型很像一只蝴蝶，大小约20光年，距离我们约2000光年。m6位于天蝎座，用双筒望远镜就可以看到，大小和满月时的 月亮差不多。与其他的疏散星团类似， m6主要由蓝色的 年轻恒星 组成，但其中最亮的 一颗看起来却是橘红色的 。

2017年5月24日 · M6也叫NGC 6405，跨度约20光年，距离我们2000光年。 在黑暗的夜空中，使用双筒望远镜很容易就能在天蝎座找到上图中的M6，它覆盖的天区约一个满月大小。 与其它疏散星团类似，M6主要由蓝色的年轻恒星组成，虽然它最亮的恒星颜色已经接近于橙色。 据估算，M6的年龄约有1亿岁。 如果能确定像M6这样的星团距离，将有助于天文学家校准整个宇宙的空间尺度。 天文地理. 微信号：tianwendilizhishi. 专注天文地理知识的订阅号. 【文章均来源于网 …

Messier 6, also known as the Butterfly Cluster or NGC 6405, is a striking open star cluster located in the constellation Scorpius. This celestial beauty was first cataloged by the Italian astronomer Giovanni Battista Hodierna in the 17th century and later independently rediscovered by Charles Messier in 1764.

The M6 globular cluster (NGC 6405), also known as the Butterfly Cluster, is an open cluster located in the constellation Scorpius. It is approximately 1,600 light-years away from Earth, with an apparent diameter of about 20 arcminutes and a total apparent magnitude of around 4.2.

< NGC List NGC 6405 Butterfly Cluster. NGC 6405 is a open cluster located in the constellation of Scorpius. The NGC is a catalog of 7,840 nebulae, star clusters, and galaxies. Here are the key stats on NGC 6405:

Messier 6 or M6 (also designated NGC 6405) is an open cluster in the constellation Scorpius. It has an apparent visual magnitude of 4.2 and its angular diameter is 25 arc-minutes. M6 lies at an estimated distance of 1600 light years. The Equinox 2000 coordinates are RA= 17h 40.1m, Dec= -32° 13´ which makes M6 best seen during the summer.
