A fact from this article appeared on Wikipedia's Main Page in the "Did you know?" column on March 31, 2011.

The text of the entry was: Did you know ... that the orbits of exoplanets Kepler-11b, Kepler-11c, Kepler-11d, Kepler-11e, and Kepler-11f (artist's depiction pictured) can fit within the orbit of Mercury?

Current status: Good article

" and is most likely a water planet with a thin hydrogen-helium atmosphere" needs a citation

"its five sister planets formed the first discovered system with more than three planets." same issue as the b one; not accurate

Done --Starstriker7^(Talk) 00:16, 25 March 2011 (UTC)[reply]

"being the most compact and the flattest system yet discovered." sounds quite subjective. Who said it?
- I agree (on flatness), unless sourced. The relative inclinations of the orbits are not known to my knowledge. Tom Ruen (talk) 01:24, 26 March 2011 (UTC)[reply]
  - "In other words, Kepler-11 has the fullest, most compact planetary system yet discovered beyond our own. " It came from this source, which was listed as reference four. --Starstriker7^(Talk) 14:42, 26 March 2011 (UTC)[reply]
    - Ok, but please specify that "in NASA's view" it is the most compact, etc. People outside NASA could disagree. Nergaal (talk) 01:25, 28 March 2011 (UTC)[reply]

"The Kepler-11 system is the first known to host more than three planets" see above

Done --Starstriker7^(Talk) 15:14, 26 March 2011 (UTC)[reply]

"Follow-up observations were conducted by facilities in California, Arizona, Hawaii, Texas and the Canary Islands." please expand

Done --Starstriker7^(Talk) 15:23, 26 March 2011 (UTC)[reply]

why is "Host star" so different from the b one? "With an apparent magnitude of 14.2, Kepler-11 cannot be seen from Earth with the naked eye" is this notable here and not in teh b one?

Done Section added to Kepler-11b as well. --Starstriker7^(Talk) 01:12, 26 March 2011 (UTC)[reply]

"a mass of 13.5 ME and a radius or 3.15 RE" same as for b. please add certainty intervals to be rigurous and not misleading

Done --Starstriker7^(Talk) 15:23, 26 March 2011 (UTC)[reply]

"grams/cc" is not a common scientific notation

Done --Starstriker7^(Talk) 01:08, 26 March 2011 (UTC)[reply]

"over 3.27 times hotter than the equivalent measurement for Earth" not necessary to have 3 sig figs here. and just say over three times than the average temperature on earth

Done --Starstriker7^(Talk) 01:08, 26 March 2011 (UTC)[reply]

"he inclination of Kepler-11c is 89º, and is thus almost edge-on as seen from Earth" super interesting: how was the inclidnation determined for something so far away? ~~also say that this is similar to Uranus~~
- This is a misunderstanding. It's the orbit that is inclided 89 degrees from the earth's direction of view, nothing to do with the rotational axis, which is unknown. This inclination fact exists because ONLY such planetary systems can be observed by the transit method used. Tom Ruen (talk) 01:21, 26 March 2011 (UTC)[reply]
  - For clarity say "orbit's inclination" Nergaal (talk) 01:25, 28 March 2011 (UTC)[reply]
How does the density compare to the gas giants in the Solar System?

Done --Starstriker7^(Talk) 15:32, 26 March 2011 (UTC)[reply]

again, add an comparative sizes image for the system

I'll pass this, but please fix the two issues I replied to. Nergaal (talk) 01:25, 28 March 2011 (UTC)[reply]
