Talk:55 Cancri

message: I can't find any source saying this is a binary star. The images at the lower end of the page show some planets circling one star, but the box on the right and the introduction say it's a binary star. What is it? \/ Thank you. Philip1201 (talk) 15:00, 16 November 2008 (UTC)

message: Pronunciation of the name 55 Cancri needs to be added to the article. Is the second 'c' hard or soft? Non-scientists like myself want to know.

message: I created the image 55Cancri System.jpg (in paint) I took some images from exoplanet.org and I change the color, order, size etc and finally I put all together, so basically I created, about the Nasa Images I know that those are free for use but I oould not find the category 1981willy 10:08, 6 June 2007 (UTC)

message: We really need a better comparison image - the scale of the system is all wrong - there is a huge gap between planets c and d, whereas in the picture the planets look equally-spaced. Chaos syndrome 13:27, 30 June 2006 (UTC)

message: Mu Arae has also got 4 planets now, so this is wrong:
"The 55 Cancri system is the first and so far only known extrasolar planetary system with four planets."
Look here: Mu_Arae —The preceding unsigned comment was added by 217.149.119.121 (talk • contribs).
:Well 55 Cancri has three confirmed planets with one possible or challenged innermost planet; to prove if it does really exist, or if it was just an error. Also 55 Cancri is no longer the "only" star with 4 planets, but was the "first star" with 4 planets discovered. But Mu Arae has four confirmed planets and with Mu Arae e as a possible exteressial life planet, similar to Earth which could be very, very interesting. --§ Alastor "Mad-Eye" Moody (talk + contribs + userboxes) 03:42, 9 September 2006 (UTC)
thread_title:  Not the only one with 4 planets 

message: Wait, the article says that the gap between c & d contains the habitable zone.  But 55 Cancri's luminosity is noticeably less than Sol's.  Wouldn't that put the habitable zone somewhere around or even inside the orbit of b?  -Tau 68.237.83.47 00:50, 29 September 2006 (UTC)

message: Looks like all the planets of 55 Cnc have relatively circular orbits. Individual planet pages should be updated.--— JyriL talk 23:33, 6 November 2007 (UTC)

thread_title: Updated orbital parameters

message: Looks like the parameters in the infobox have been updated to include citations (which is good). Unfortunately the text has not been, so we've now got conflicting estimates for quantities such as age and metallicity in the text and the infobox. If you're going to change the infobox, please make sure the article is still self-consistent (and vice-versa)! Chaos syndrome 00:02, 9 November 2007 (UTC)
replies: text: To be blunt, your new layout looks absolutely hideous on my browser. It pushes all of the lead text down past the end of the table. I don't find this to be an acceptible solution. Also this is a page in work. Rather than complaining about a page in an intermittent stage, why don't you fix the issues yourself? It's been less than one day since the references have been added into the infobox. Good grief. Anyway, I find myself suddenly disinterested in putting in more work on this page. Bye. — RJH (talk) 19:00, 9 November 2007 (UTC)

thread_title:  OMG, really? 

message: According to an HST Search it looks like there are images of 55 Cancri taken by Hubble (which would be in the public domain). I don't have an account on their data retrieval system, but it seems like someone should make an effort to retrieve at least one actual image of the star system.

message: 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) 01:19, 3 March 2009 (UTC)

message: hi, 
I wanted to point out that the image at the right side, that displays the location of the star 55 Cancri in a small star-map is misleading. 
The legend says : "Location of 55 Cancri (circled)" but in that image there are more circles, as the one around M44. When the user clicks on the image, the svg image displayed in the navigator does not show the red circle that surrounds 55 Cancri.  158.169.150.18 (talk) 14:21, 7 June 2021 (UTC)
replies: text: Unfortunately the image is just a map and the circle only displays in this article and on the thumbnail.  I have changed the caption to make it clearer which circle identifies this star.  Lithopsian (talk) 19:40, 7 June 2021 (UTC)
