Hubble Space Telescope observation for a Jupiter-sized companion[edit]

I believe that the following statement:

No Jupiter sized object could be detected by the recent research using the Hubble Space Telescope.

was based upon information included in the SolStation article. The latter references Schroeder et al, 2000, but in reading through that journal article, GJ 887 was not included as one of the program stars. Therefore I believe that the SolStation article is in error and so I removed the above text from this article.

This statement is likely from the same source, and can't be readily cross-checked:

Its closest neighbor is the EZ Aquarii Triple Star System, 1.29 pc or 4.21 ly away.

It too was removed.—RJH (talk) 22:10, 20 January 2010 (UTC)

The closest currently known star system to Lac 9352 is indeed EZ Aqr ABC at ≈4.1 ly. Solstation used Chview simulation program to show it. --Yigor (talk) 08:00, 15 April 2010 (UTC)
I haven't found SolStation to be a completely reliable source. It can be a good starting point, but I have found a few errors on the site. (As per the example at the start of this section.) We should probably reference the Chview site.—RJH (talk) 16:08, 15 April 2010 (UTC)
Yeah, it's not obvious at all, U should put at least 50 nearest star systems on a 3D-map to be sure. Actually, my own simulations give also GJ 1 and SCR 1845-6357 at ≈4.3 ly from Lac 9352. In addition, HIP parallaxes used by RECONS and Solstation for some stars are now improved by the new HIP2 reduction. --Yigor (talk) 18:41, 17 April 2010 (UTC)
Well, finally, I put the info about its closest neigbour (EZ Aqr) referring to the ChView simulation. --Yigor (talk) 18:32, 20 April 2010 (UTC)
Thanks. I'm not really sure why it is of interest, unless the nearest star is especially close.—RJH (talk) 19:52, 20 April 2010 (UTC)
Yeah, anyway, let it be like that until someone finds a closer star or brown dwarf. lol ;) --Yigor (talk) 21:02, 20 April 2010 (UTC)
Actually, one of easy consequences of this proximity is that the constellation Piscis Austrinus is not far away from Aquarius! :D --Yigor (talk) 21:19, 20 April 2010 (UTC)
