# Talk:47 Ursae Majoris b

Someone has grossly mistaken 47 UMa b for 47 UMa c and vice versa. This unfortunately is common because some people believe the planet designations should be ordered from innermost outward, however in fact they are ordered by order of discovery. See: http://exoplanet.eu/star.php?st=47+Uma to see how the articles here on these planets have been wrongly swapped around. Exoplanet.eu is the authority on extrasolar planetary designations, so can someone please fix this? I noticed the planets are showing the wrong mass and inclination among other wrong data that is vicey versa. 75.67.80.68 (talk) 09:31, 4 July 2009 (UTC)

After review, I've determined that this article meets the qualifications for GA status. It is well written, well referenced, and comprehensive. I'm "Mass Passing" this article along with 2 related articles. The entire list is below. If new developments arise that would effect the references or comprehensiveness of this article, it may affect the others as well.

These articles are good examples of well written articles on a short subject. They represent a comprehensive view of a relatively new observation, in a concise manner. Future additions could include images such as diagrams comparing planetary size / orbital distances, etc. If you have any questions on my rationale for promotion, please leave a message on my talk page.

however, this article http://www.nature.com/nature/journal/v385/n6613/abs/385234a0.html mentiones how a moon around this planet might support surface liquid water if large enough. Im not sure why this is the case if its outside the habitable zone, however this article http://www.physorg.com/news65376545.html mentiones how a moon system with sufficient eccentricity of orbits to allow for enough heat to be created from the tidal heating might stretch the habitable zone outward. --89.172.84.10 09:48, 31 May 2007 (UTC)
- Yes, the additional warming comes from sunlight reflected from the gas giant onto the moon surface, although tidal heating will also provide some geoconvection that would help generate a geomagnetic field for the moon to shield itself from radiation.75.67.80.68 (talk) 09:36, 4 July 2009 (UTC)

As part of the WikiProject Good Articles, we're doing sweeps to go over all of the current GAs and see if they still meet the GA criteria. I'm specifically going over all of the "Planets and Moons" articles. I believe the article currently meets the criteria and should remain listed as a Good article. I have made several minor corrections throughout the article. Altogether the article is well-written and is still in great shape after its passing in 2006. Continue to improve the article making sure all new information is properly sourced and neutral. If you have any questions, let me know on my talk page and I'll get back to you as soon as I can. I have updated the article history to reflect this review. Happy editing! --Nehrams2020 (talk) 09:34, 20 February 2009 (UTC)

There is a move discussion in progress on Talk:Upsilon Andromedae d which affects this page. Please participate on that page and not in this talk page section. Thank you.  —RMCD bot 02:59, 17 December 2015 (UTC)
