Not the first extragalactic globular cluster

[edit]

As early as 1932, Edwin Hubble discovered 140 extragalactic globular clusters around the Andromeda Galaxy.[1] I think the author meant that M54 is the first former 'Galactic Globular Cluster' correctly recognized to belong to a dwarf galaxy orbiting our Galaxy. --Diamonddavej (talk) 01:34, 19 June 2011 (UTC)[reply]

Several globular clusters in the Large and Small Magnellic Clouds as well as in the Fornax Dwarf Spheroidal were discovered in the 19th century are in the NGC catalogue. I don't know when they first associated with their host galaxies though but at least before the 1950s (e.g. Gascoigne & Kron 1952[2]). Korandder (talk) 13:52, 15 October 2015 (UTC)[reply]


Radius

[edit]

What is the source of the radius quoted in the info box? Also what sort of radius is it? Core, half-light, tidal or some other one? Korandder (talk) 13:48, 15 October 2015 (UTC)[reply]

Numbers dont add up

[edit]

Figures on the SagDEG article place it at 70,000 LY from Earth, with a diameter of 10,000 LY, with "M54 apparently at its core". Yet this article here M54 gives a distance on 87,000 LY, which would put it well beyond the core.

This comment also made on the SagDEG article. — Preceding unsigned comment added by 2001:8003:E448:D401:E8BE:3E5F:C4C2:ACB9 (talk) 03:52, 7 October 2019 (UTC)[reply]
