Distance from Earth

[edit]

The third reference doesn't say that the planet is about 100 light years from Earth. The article doesn't give any distance figures at all. Is there a confirmed distance? — Preceding unsigned comment added by 208.196.60.50 (talk) 18:41, 14 November 2012 (UTC)[reply]

You are right. I'm parsing the paper and it seems there are several informed guesses at the distance but no real confirmed value. I'll edit to reflect this fact. --Cyclopiatalk 18:46, 14 November 2012 (UTC)[reply]
My mistake. Thanks for catching and correcting it. I haven't had a chance to read through all the sources yet, but I'll put some more work into it when I get back from work tonight. Braincricket (talk) 18:56, 14 November 2012 (UTC)[reply]
Eso reports its distance to earth to be 100 light years too: [1] Amphicoelias (talk) 18:24, 15 November 2012 (UTC)[reply]
The article now reports the estimates from the discovery paper, which seem the most reliable source so far. --Cyclopiatalk 19:45, 15 November 2012 (UTC)[reply]
"If this object is actually a rogue planet [...], then it is the closest that has ever been spotted." - this statement has become outdated. Shorr (talk) 23:42, 10 October 2013 (UTC)[reply]
Updated the info -given the uncertainities I think it's hard to say definitely which is closer, but paragraph now just refers it as "among the closest" - and mentions the new object.--cyclopiaspeak! 16:24, 11 October 2013 (UTC)[reply]

Image editing

[edit]

The central blue dot in the image is *very* dim, which means it is almost impossible to see when it's not enlarged. Should we add a coloured circle or arrow to point at it? I suspect some readers can confound it with the bright cyan spot. --Cyclopiatalk 17:29, 16 November 2012 (UTC)[reply]

Direct Imaging

[edit]

Are planets like these good candidates for direct imaging since there is no parent star? — Preceding unsigned comment added by 216.246.130.20 (talk) 19:34, 1 December 2012 (UTC)[reply]

Brown dwarf?

[edit]

Article states that the body is a brown dwarf, but apparently cites this to a (non-technical) article that states that it probably isn't ("The team believe it has [...] mass between four and seven times that of Jupiter - well short of the mass limit that would make it a likely brown dwarf"). Unless something has changed since that article has been published and the mass estimate has been revised upwards, should this assertion not be removed? 212.159.69.4 (talk) 00:03, 23 December 2012 (UTC)[reply]

A very good point. Given that there is only a 13% chance that this object is a brown dwarf according to the paper, that brown dwarf statement should be removed. I will update the article. Martin Cash (talk) 17:09, 12 December 2013 (UTC)[reply]
