The
planet,
Kepler 452 b, is likely rocky and
orbits in its
star's habitable zone where liquid water can exist
Under K2,
Kepler won't stare at the same patch of sky for as long, so it will be restricted to hunting for
planets that
orbit their
stars much more closely than Earth does the sun.
Early in its mission,
Kepler managed to find some tantalizing worlds, a handful of supersize cousins of Earth, most of them in clement
orbits around smaller, cooler, quieter
stars than the sun called M and K dwarfs, but all the setbacks made finding smaller Earth - sized
planets around sun - like G
stars a very tall order.

planet,
Kepler - 186f, might
orbit outside its

It's a basic bias in transiting exoplanet surveys: Larger objects will produce larger changes in a

orbits the sun.

TIGHT FIT The
star Kepler 11 (illustrated) is home to six
planets, five of which would fit inside the

William Borucki, of the NASA Ames Research Center in Mountain View, California, has captured the astronomy prize for two achievements: conceiving the observational technique of transit photometry that raised the tantalizing prospect of sighting Earth - like
planets orbiting other
stars, and leading the 25 - year - long development of the
Kepler mission, which in 2009 placed a telescope in space to make those observations.
The
Kepler 11 system is unique for several reasons: For starters, it is among the largest collections of worlds known outside our own solar system, and all six of the
planets Kepler has found there are aligned so that their
orbits carry them across the face of their host
star from
Kepler's vantage point.
Borucki says it will be a few years yet before
Kepler is able to identify a true Earth analogue — a small
planet on a one - Earth - year
orbit around a sunlike
star.
All five of the new extrasolar
planets, or exoplanets, as well as one more world whose properties are not yet fully understood,
orbit a sunlike
star called
Kepler 11, some 2,000 light - years away.
The
planet designated
Kepler - 186f, however, is earth - sized and
orbits within the
star's habitable zone.
