NGC 6025 - Open Starcluster in the Constellation Southern
Triangle |
|
Description of
object:
The open star cluster
NGC 6025 in the constellation Triangulum Australe has a distance of roughly
2700 light years from the earth. The diameter of the star cluster in the sky is
roughly 12 arc minutes, which is equivalent to an absolute diameter of 9 light
years. Its age is estimated to be 125 million years.
Analysis of
the chemical composition of members of the cluster show that NGC 6025 has the
highest metal content of all currently known open star clusters in our milky
way. In the field of astronomy all elements more heavy than Helium are counted
as metals. The so called metallicity of open star clusters is an important
number to tests theories about the formation and evolution of the galactic
disc. |
