Who knows what they could of found?

Earth type planet in our back yard?

Maybe a new type of exotic planet?

Maybe a replica of our solar system?

Maybe an open cluster with each star having 1-2 earth sized planets?

Maybe they have finally been looking long enough that they are finding Jupiters, Jupiters everywhere! Oh, or Neptunes too...

Maybe they have found a star with 2 orbital planets at 90 degree angles to one another?

... Maybe kepler is dead? In that case, this would be a final farewell and a ceremony to look back on the achievements of the little sat.

(Or many they got funding for spaceX to launch another satalight!)

Close Earth analogue found around a G2 (sol like) sun with a 385 day length. Kepler 452 b. Slightly older than Earth, it has spent 6 Billion years in it's habitable zone.

Probably 5x(+ or - 2) the mass of Earth and only an even money chance of it being rocky. (meh)

it said that it is 5 times more massive than earth, so not sure if the density will change or not...

Surface gravity?

The most probably with that mass and even a bit lower light pressure, that it will have a more dense atmosphere.

How much it will be hard to know.. but if the atmosphere is very dense, then it will have high surface temperatures as venus.

Interesting news!

Someone mentioned Kepler not being able to detect planet atmospheres, but I've seen several scholarly articles related to transit detection to the contrary. I'll guess this announcement is the proof in that pudding.

Its ESI is only 0.69? That seems a bit low. I guess they're waiting for more data before they update it.

Well, it's much larger than earth. In terms of size, there have been better candidates.

Arent they just detecting that there are atmospheres, rather than actually seeing what the atmospheres are made of?
