# Talk:47 Ursae Majoris

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.

47 Ursae Majoris
47 Ursae Majoris b
47 Ursae Majoris c
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.

I find the following sentences difficult to understand:
"Using this model of this planetary system found out it is 100,000 times more likely to have three planets than two planets."
and
"It would be the longest-period planet discovered by radial velocity method, although longer-period planets only priorly been discovered by direct imaging and pulsar timing."
If I have understood them correctly, would they not be better expressed as: 
"Using this model, the planetary system is 100,000 times more likely to have three planets than two planets."
and
"It would be the longest-period planet discovered by radial velocity method, although longer-period planets have previously been discovered by direct imaging and pulsar timing." ?

I have created an orbit diagram for this system based on the Wittenmyer paper (47 UMa c at 7.73 AU), however since the diagram is now hosted on Wikimedia Commons, I am currently unable to upload it for the next 4 days (due to restrictions in place on modifying images with new accounts).

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. I would recommend going through all of the citations and updating the access dates and fixing any dead links. 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) 01:12, 3 March 2009 (UTC)

Just read 47 Ursae Majoris to be renamed Chalawan, after an extinct crocodylian found in Thailand, and named after a mythical crocodile king; two of the exoplanets will be named after his human wives,  Thapao Thong and her sister Taphao Kaew.

Why does this article refer to the star's age in multiples of millions of years? It's technically correct, but it's easy to misread it and underestimate the orders of magnitude being discussed, since most astronomy articles on Wikipedia use gigayears instead (e.g. 8.7 Gyr rather than 8,700 million years). Is there a reason for this? --203.57.211.237 (talk) 11:12, 16 December 2016 (UTC)
