Lyra is the constellation which can be seen from northern hemisphere from spring to autumn. Also recognized by International Astronomical Union. It is one of the closest constellation to the Earth. Lyra is composed of the stars called Vega, Sheliak, Sulafat, Kepler -37, Kepler - Kepler - 62. The last two have been discovered by Kepler Spacecraft in 2013.

Lyra also consists of exoplanets which have been observed by Kepler Mission like Kepler 7b, Kepler 8b.

Especially the planets orbiting the Kepler 62 star which are Kepler-62e, Kepler-62f are considered to be located in the habitable zone of the system and scientists specify that these planets are solid and ropcky and also include liquid water in order to sustain life on them. The distance of the Kepler 62 system to the Earth is 1200 light years.

Probably just a wording issue, but that doesn't sound right.

A constellation is composed of specific visible stars defined in times long ago.
Why would the composition of a constellation change? Especially with stars that aren't naked eye.

If you mean they contain those Kepler stars, then why not mention the plethora of other stars that lie within the boundaries of Lyra?

I'm also curious why you mention these planets in particular when there are also other rocky exoplanets discovered so far (http://en.wikipedia.org/wiki/List_of_nearest_terrestrial_exoplanet_candidates).

"It is one of the closest constellation to the Earth"I find this statement worrying as surely a constellation is an arbitory collection of stars that are not in a grouping, only a sight grouping from earth, take the consolation of Taurus Aldebaran is 66.7 ly Gamma Taurus is 161 ly Zeta Taurus is 446 ly. So as you see stars of a constellation are not in a grouping like they are in a globular cluster.
