NGC 121 is a globular cluster of stars in the southern constellation of Tucana. It is the oldest globular cluster in the Small Magellanic Cloud (SMC), [5] which is a dwarf satellite galaxy of the Milky Way. This cluster was first discovered by English astronomer John Herschel on …

ngc 121（eso 50-sc12）是杜鹃座的一個球狀星團，是smc的一部分。 星等 為11.2， 赤經 為26分47.1秒， 赤緯 為-71°32'12"。 在1835年被 約翰·弗里德里希·威廉·赫歇爾 發現。

2023年10月31日 · With an object like NGC 121, which lies close to the Milky Way, Hubble is able to resolve individual stars and get a very detailed insight. NGC 121 is around 10 billion years old, making it the oldest cluster in its galaxy; all of the SMC's other globular clusters are …

This image shows NGC 121, a globular cluster in the constellation of Tucana (The Toucan). Globular clusters are big balls of old stars that orbit the centres of their galaxies like satellites — the Milky Way, for example, has around 150. NGC 121 belongs to one of our neighbouring galaxies, the Small Magellanic Cloud (SMC).

Abstract: We present observations for three star clusters, Kron 11, Kron 63 and NGC 121, in the Small Magellanic Cloud. We have studied their structure and derived their fundamental parameters by means of their luminosity functions, their colour magnitude diagrams and the Padova suite of isochrones.

NGC 121 is a Globular Cluster in the Tucana constellation. NGC 121 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. Given its visual magnitude of 11.24, NGC 121 is visible with the help of a telescope having an aperture of 6 inches (150mm) or more.
