    1400 light years!

    Roughly speaking how far is 452-b from earth?

    We refer to 452b as elder cousin because the star and planet are 1.5 billion years older than Sun and Earth.

    So, is orbiting a 'sun' into the habitable zone, that's why we called "Earth's elder cousin"? Is all th info we have?

    3.5 years was believed to be time to detect small planets in habitable zone.

    Why was the Kepler mission only planned for 3 and a half years? Also, how long is the expected lifespan of the craft?

    We demand very high confidence level for confirmation; requires observing from ground; Cygnus visible in summer only.

    is in our Milky Way Galaxy about 1,400 light years from us.

    In which galaxy, nd how many light years away, coz it maybe possible we r looking at what should not be there nymr now?

    It is unlikely to be tidally locked in such a long period orbit.

    If you know the age of the star, can you estimate whether it would be tidally-locked?

    In astronomer-speak, "A" refers to the star.

    Why is it 452b and not 452a, since it's the first planet detected in that system?

    These are really hard to find (& we've found 11 other around M & K stars) so it means 15-25% of stars have such.

    U've found 1 such planet after years looking at stars inc. M dwarfs. What does this tell us about the abundance of such planets?
