Bigger, Older Cousin to Earth

I wonder if there is live on this Cousin of ours Question



http://www.nasa.gov/press-release/nasa-kepler-mission-discovers-bigger-older-cousin-to-earth

  • The newly discovered Kepler-452b is the smallest planet
    to date discovered orbiting in the habitable zone
    -- the area around a star where liquid water could pool on the surface of an orbiting planet --
    of a G2-type star, like our sun.

  • Kepler-452b is 60 percent larger in diameter than Earth and is considered a super-Earth-size planet.
    While its mass and composition are not yet determined, previous research suggests that planets
    the size of Kepler-452b have a good chance of being rocky.

  • While Kepler-452b is larger than Earth, its 385-day orbit is only 5 percent longer.
    The planet is 5 percent farther from its parent star Kepler-452 than Earth is from the Sun.
    Kepler-452 is 6 billion years old, 1.5 billion years older than our sun, has the same temperature,
    and is 20 percent brighter and has a diameter 10 percent larger.

I'm no expert in this but
■ Wouldn't we be seeing if from 1,400+ years ago, it could no longer exist.
■ It would take a several million years to travel there without a sci-fi shortcut.
■ If we discovered a message from their planet, sentient life could no longer exist, or could be extremely more advanced than us.
■ If there is/was life on their planet, they could be coming to our planet expecting to colonize here.

I'm a little confused, just about every other story states it's 1,400 light years away, even the wiki
https://en.wikipedia.org/wiki/Kepler-452b

The nasa.gov page says it's 1,400 light years from Cygnus, not us.

Maybe there is. Who knows? It wouldn't surprise me. Wikipedia says it's No. 6 on the list of Similar-to-Earth planets. The only downside is the distance: 1.400 light years is a bit far from here.

No. 1 on that list is Kepler 438b. And at 470 light years from us, it's practically around the corner. Time to engineer a rocket to go there.

There is a list .. EARTH is the most inhabitable planet (#1)

https://en.wikipedia.org/wiki/List_of_potentially_habitable_exoplanets

I prefer Gliese_667_Cc



https://en.wikipedia.org/wiki/Gliese_667_Cc

It's even better inhabitable than Keppler 452 or 438b and a much shorter distance (24 light years)

It will take us 6.5 days travel at warp 11 Razz
