NASA's Kepler space telescope ran out of fuel in October last year. Data gathered during the course of its scientific mission, however, paved way to the discovery of a new exoplanet. Planet K2-288Bb The newly identified planet dubbed K2-288Bb is twice the size of the Earth. It lies within its host star's habitable zone, which means the planet may have liquid water on its surface. It could either be rocky like our home planet or gas-rich like Neptune. The new world is located 226 light-years away in the constellation Taurus and lies in a stellar system called K2-288. The stellar system has two dim, cool M-type stars about 5.1 billion miles apart, which is about six times the distance between Saturn and the sun. The brighter of the pair is about half as large and massive as the sun while the dimmer one is about a third of the solar mass and size. K2-288Bb orbits this smaller and dimmer star every 31.3 days.
