Orbital size

How far is it from the black hole? --JWB (talk) 13:46, 4 July 2016 (UTC)[reply]

The orbit is highly eccentric, but several hundred AU. Lithopsian (talk) 20:31, 30 July 2018 (UTC)[reply]

What will eventually happen to it? Will it eventually fall into the black hole? — Preceding unsigned comment added by 2600:1700:37E0:8C60:589:F8F5:8FC4:2BA0 (talk) 03:18, 6 December 2018 (UTC)[reply]

Move to S55

Two naming schemes are used for the stars orbiting SgrA*: Sxx and S0-yy. Wikipedia currently uses a mix of these, though I think this article is the only one left that uses the S0-yy scheme. Sxx seems to be winning in the literature, and the most complete published data for these stars uses the Sxx scheme. Therefore, many stars only have a name in the Sxx scheme, and not in S0-yy. I propose that we standardize on the Sxx scheme, and I will move this page to S55 in a while if there aren't protests. Amaurea (talk) 19:34, 15 February 2020 (UTC)[reply]

Before you move, can you please supply a reliable reference that these two names are for the same stars? As existing references call this S0-102. Graeme Bartlett (talk) 19:47, 15 February 2020 (UTC)[reply]

See page 9 here: "In addition, stars without radial velocity but large phase coverage like S55 (S0-102 in Meyer et al. 2012) can be useful for a multi-star ﬁt". You can also look at the table in the Sagittarius A* article to see the correspondence between the name systems. Amaurea (talk) 01:56, 16 February 2020 (UTC)[reply]
