New Super-Earth Detected Within The Habitable Zone Of A Nearby
Star

An international team of scientists has discovered a potentially
habitable super-Earth orbiting a nearby star. With an orbital
period of about 28 days and a minimum mass 4.5 times that of the
Earth, the planet orbits within the star's "habitable zone",
where temperatures are neither too hot nor too cold for liquid
water to exist on the planet's surface. The researchers found
evidence of at least one and possibly two or three additional
planets orbiting the star, which is about 22 light-years from
Earth.

The team includes UC Santa Cruz astronomers Steven Vogt and
Eugenio Rivera and was led by Guillem Anglada-Escud=E9 and Paul
Butler of the Carnegie Institution for Science. Their work will
be published by Astrophysical Journal Letters, and the
manuscript will be posted online at:

arxiv.org/archive/astro-ph

The host star is a member of a triple-star system and has a
different makeup than our Sun, with a much lower abundance of
elements heavier than helium, such as iron, carbon, and silicon.
This discovery indicates that potentially habitable planets can
occur in a greater variety of environments than previously
believed.
