# Talk:Kepler-9c

Although the text states that the planet is about 15% the size of Jupiter, looking at the image in the infobox one gets the impression that it's only 15% smaller, which is a different thing. Could somebody with more knowledge than me about this check this please (before it goes active on DYK preferably). --Crusio (talk) 00:17, 19 February 2011 (UTC)
You are correct. The page author confused Kepler 9-c with Kepler 9-d.

I have to be more careful. I will be in the future. --Starstriker7(Talk) 05:46, 22 February 2011 (UTC)

The periodical variations are oscillatory, as stated even in the MSNBC article. That means the shortening of the orbital period will eventually be reversed. I clarified some of the statements which unfortunately had already found their way onto the Main Page.  —Preceding unsigned comment added by 68.44.40.236 (talk) 19:19, 20 February 2011 (UTC) 

As the article currently stands, the "stable orbit" is shortened by 39 minutes each "year", with no oscillation mentioned.--Wetman (talk) 20:49, 20 February 2011 (UTC)
