Talk:List of nearest known black holes

Why no black holes closer to us
Why is there no black closer than 2000 ly away from us? Is it because none has been detected yet, or do scientists really believe there is no black hole within this radius? Thinking of the large number of short-living massive stars within this radius, it appears odd if there were no black holes. T om ea s y T C 20:17, 20 February 2016 (UTC)

More black holes to add
This needs improvement, there are more black holes to add Such as v4641 sgr. - anonymous 16:27, 19 July 2016‎

Incorrect mass for A0620-00 ?
The article for A0620-00 says it's 6.6 Solar masses, not 11; and this seems to be confirmed in the paper linked in the article. --TiagoTiago (talk) 06:06, 17 January 2018 (UTC)

Please fix table formatting
The table is badly mangled. Fig (talk) 09:27, 28 January 2018 (UTC)

Sagittarius A* sorts as smallest.
If you sort by mass this table sorts Sagittarius A* as smallest. The mass should be listed in a different format so the sort works. Maybe 4.1x10^6? I don't know enough about how the sorting function on these lists work. — Preceding unsigned comment added by 2600:1700:8310:B1A0:F982:7B69:89AD:3506 (talk) 03:56, 29 November 2019 (UTC)

What is meant by "relatively near?"
There is no clear definition of what is being categorized as close to the solar system. The last two entries include black holes that are over 20,000 ly away. I don't see how this would be considered "near" when the Milky Way only has a radius of about 53,000 ly? CayenneEMatt (talk) 00:47, 10 May 2021 (UTC)
 * Article should define the cut-off distance. Is it 30,000 light years, or should it be something less? Nurg (talk) 04:04, 7 November 2022 (UTC)

LB-1 not generally thought to contain a black hole
LB-1 in recent reviews is thought to be an unusual binary of two stars and does not contain a black hole. - anonymous — Preceding unsigned comment added by 108.31.90.200 (talk) 04:55, 15 July 2022 (UTC)

GRO J0422+32/V518 Persei has a significantly smaller mass, so it is not a black hole.
