Kepler-452 is a G-type main-sequence star located about 1,810 light-years away from Earth[1] in the Cygnus constellation.

[6][7] Alongside this, the star is approximately six billion years old and possesses a high metallicity.

The transit method that Kepler uses involves detecting dips in brightness of stars.

These dips in brightness can be interpreted as planets whose orbits pass in front of their stars from the perspective of Earth, although other phenomena can also be responsible which is why the term "planetary candidate" is used.

[8] Following the acceptance of the discovery paper, the Kepler team referred to the star as Kepler-452, which is the normal procedure for naming exoplanets discovered by the spacecraft.

This planet is mostly known for its characteristics similar to Earth, most notably its size, orbit and stellar flux.

However, because of its mass (estimated to be about 5 ME), it may be able to prevent succumbing to the runaway greenhouse for a limited amount of time (at most about 500 million years).
