NGC 2360 (also known as Caroline's Cluster[3] or Caldwell 58) is an open cluster in the constellation Canis Major. It was discovered on 26 February 1783 [4] by Caroline Herschel, who described it as a "beautiful cluster of pretty compressed stars near 1/2 degree in diameter". [5] .

2025年2月5日 · Caldwell 58, also known as NGC 2360 or Caroline’s Cluster, was discovered by and named after the German astronomer Caroline Herschel in 1783. The younger sister of famed astronomer William Herschel, Caroline was the first woman to win the prestigious Gold Medal of the Royal Astronomical Society.

NGC 2360，也稱為 卡洛琳的星團[3]，是位於 大犬座 的一個 疏散星團。 它是卡洛琳赫歇爾在1783年2月26日發現的 [4]，她寫道："一個被擠壓在直徑0.5度，標致的漂亮" [5]。 她的筆記一直被忽略，直到她的哥哥 威廉·赫歇爾 在1786年出版，包含1000個星雲和星團的目錄中，大家才知道她是發現者 [4]。 這個星團位在 天狼增四 （大犬座γ）的東方3.5度， 食雙星 大犬座R 西北方1度之處；它聚合的 視星等 為7.2等 [5]。 它的視直徑為13角分 [2]。 在這個星團西側邊緣，5.5等的 …

The open cluster NGC 2360 is located in the constellation Canis Maior. The best time for observation is in the months from October to April.

NGC 2360 is a Open Cluster in the Canis Major constellation. NGC 2360 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 7.2, NGC 2360 is visible with the help of a small binocular.

C58 (NGC 2360) – Caroline’s Cluster. Caldwell 58 is an open cluster — a group of stars loosely bound together by gravity. Astronomers used Hubble to study white dwarfs in C58 and better understand the age of our galaxy.

2023年8月9日 · Taken by the Digitized Sky Survey (DSS), the ground-based image of Caldwell 58 (NGC 2360) in the lower left shows the location of Hubble’s Advanced Camera for Surveys (ACS) observation of stars in the cluster. ACS uses two imaging chips that are close but not immediately next to each other, leaving a small gap in the full image.

February 5–12, 2015: The double star ADS 5951 and open cluster NGC 2360, both in Canis Major, each offers small-telescope owners stunning views, while large-telescope owners can seek out...

2024年4月10日 · NGC 2360, also known as ‘Caroline’s Cluster’, is an intermediate cluster that is located in the southern constellation Canis Major. It was first discovered by Caroline Herschel, however was never officially brought to attention until her brother William included NGC 2360 in his 1783 catalog of 1000 star clusters and nebulae.

2012年11月1日 · We derive astrophysical and structural parameters of the poorly studied open clusters NGC 6866, NGC 7062, and NGC 2360 based on filtered 2MASS (J, J − H) diagrams, and stellar radial density profiles. The field star decontamination technique is utilised for selecting high-probability cluster members.
