Lede

"Kepler-9b is one of the first exoplanets discovered by NASA's Kepler Mission, and is located around the star Kepler-9 in the first extrasolar system discovered to have multiple transiting planets. It is the largest planet yet discovered in the Kepler-9 system, and has a mass slightly smaller than that of Saturn's."
This article might have lost several readers with that first sentence. They would have clicked on "exoplanets" and never come back. It would have been better to define the term than to rely on it; furthermore, "the star ... in the first extrasolar system ..." is kind of awkward, and "transiting" is the detection methodology (and use of its definition as an adjective is like a jargon, possibly confusing to layman readers). Suggest: "Kepler-9b is one of the first planets discovered outside the solar system (exoplanets) by NASA's Kepler Mission. It revolves around the star Kepler-9 within the constellation Lyra. Kepler-9b is the largest of three planets detected in the Kepler system by transit method; its mass is slight smaller than the solar system's Saturn."

Alright. I took your suggestion and tweaked it a bit. How does it look? --Starstriker7^(Talk) 01:59, 18 February 2011 (UTC)[reply]

I am not too enamored with leaving out clarifying Saturn (and likewise later Jupiter), but arguments can be made that our system's celestial bodies are common knowledge to any one that would come read the project, so this can be left as future improvement or ignored.

Nomenclature and history

~~"... star Kepler-9. Kepler-9, in turn ...": Two "Kepler-9"s in a row is a bit repetitive.~~

Fixed. --Starstriker7^(Talk) 02:01, 18 February 2011 (UTC)[reply]

"The system in particular was flagged as one of five systems that appeared to have held more than one transiting exoplanet.", "It was the part of the first confirmed star system in which multiple planets transited the same star."
Similar to the issue in the lede, by using "transiting" as the adjective, this article is cast into a niche—astronomy. Use "transit" in its context, e.g. "The system in particular was flagged as one of five systems that appeared to have more than one exoplanet detected by transit method.", "It was the part of the first confirmed star system in which multiple planets were detected to transit the star."

The concept is explained later on in the section, so it doesn't really rely totally on the detection methods article. --Starstriker7^(Talk) 02:01, 18 February 2011 (UTC)[reply]

Generally, one does not launch a technical term without explaining it first (the "putting the cart before the horse" analogy comes to mind). However, since this is a short article and the lede already states the transit method, this can be overlooked. Jappalang (talk) 05:54, 18 February 2011 (UTC)[reply]
