NGC 2266 is an open cluster [5] of stars in the constellation of Gemini. It was discovered by German-British astronomer William Herschel on 7 December 1785. [6] This is a relatively dim cluster with an integrated visual magnitude of 9.5 and an angular size of 5.0′. The stellar members can be readily resolved with an amateur telescope. [3]

Take for example this star cluster known as NGC 2266 (item number 2,266 in the NGC compilation). It lies about 10,000 light-years distant in the constellation Gemini and represents an open or galactic cluster. With an age of about 1 billion years, NGC …

We present deep CCD photometry (V 21 mag) in BVRI Johnson-Cousin filters supported with 2MASS JHK data set for the old open star cluster NGC 2266. The cluster’s parameters such as reddening, distance, metallicity and age, etc ..., are derived using two color diagrams in optical and near-infrared bands.

Also known as Melotte 50, NGC 2266 is a small, compact star cluster made up of more than 190 stars, most of them main sequence stars, and a clump of 11 red giants. Its age is estimated at 1.2 billion years, about the age of the Hyades or Praesepe.

2024年10月26日 · NGC 2266 is also catalogued as Melotte 50. It is an open cluster located in Gemini and lying about 10,603 light years from Earth. It is estimated to be a little more than 81 million years old, similar to the Hyades and Beehive clusters, though some older estimates put its age at around a billion years.

NGC 2266 is a Open Cluster in the Gemini constellation. NGC 2266 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its visual magnitude of 9.5, NGC 2266 is visible with the help of a binocular with a 80mm aperture or a small telescope.

From Redmond , NGC2266 will become visible at around 20:34 (PDT), 67° above your south-western horizon, as dusk fades to darkness. It will then sink towards the horizon, setting at 04:16. All times shown in Redmond local time.

1995年10月27日 · The Open Star Cluster NGC 2266 lies in a distance of about 3.4 kpc towards the constellation Gemini. Its apparent diameter is just about 5'. It belongs to the population of old open star clusters in our galaxy, i.e. ages of one billion years or even older (Phelps et al., 1994).
