NGC 2158 is an open cluster in the constellation of Gemini. It is, in angle, immediately southwest of open cluster Messier 35, and is believed to be about 2 billion years old. [2] The two clusters are unrelated, as the subject is around 9,000 light years further away.

NGC 2158 is a Open Cluster in the Gemini constellation. NGC 2158 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year. Given its visual magnitude of 8.6, NGC 2158 is visible with the help of a binocular with a 60-70mm aperture or a small telescope.

M35 (also cataloged as NGC 2168) is a mere 2800 light-years distant, with 400 or so stars spread out over a volume about 30 light-years across. Bright blue stars frequently distinguish younger open clusters like M35 , whose age is estimated at 150 million years.

NGC 2158 is a very rich and distant star cluster. Several thousand stars in an area of about five minutes of arc. The unusually large number of stars and their symmetrical distributions suggest that this is an intermediate stage from an open star cluster to a globular cluster, but the cluster does not show the central density typical of ...

M35 and NGC 2158 are two neighboring open clusters located in the constellation Gemini and are often observed together by astronomy enthusiasts. M35 (upper right in the image) is approximately 912 par...

2025年1月1日 · NGC 2158 Open Cluster in Gemini - posted in Experienced Deep Sky Imaging: Lets bring in the new year, with my first quick image of the year. This is NGC 2158, an open star cluster in the constellation of Gemini. It is believed to be about 2 billion years old and is located around 11,000 light years away and 8 light years in diameter.

2013年1月3日 · NGC 2158 is four times more distant than M35, over 10 times older, and much more compact with many more stars in roughly the same volume of space. NGC 2158's bright blue stars have self-destructed , leaving cluster light to be dominated by older and yellower stars.

NGC 2158 is an Open Star Cluster located in the constellation of Gemini in the northern hemisphere. NGC 2158's distance from Earth is 11,000.00 light years. NGC 2158 is called NGC 2158 in the New General Catalogue (NGC).

From Redmond , NGC2158 will become visible at around 20:34 (PDT), 62° above your south-western horizon, as dusk fades to darkness. It will then sink towards the horizon, setting at 03:22. All times shown in Redmond local time.

This wellknown open cluster, situated very close to famous M35 (NGC 2168), was considered as a globular by Rosino (1954), see also Sawyer Hogg (1959). Despite this, its nature as an old Galactic open cluster is established with certainty; its …
