NASA scientists have found 219 possible new exoplanets in our galaxy, including 10 relatively small, rocky and possibly habitable planets similar to our own.Kepler research scientist Susan Thompson, the lead author of the catalogue study, said her team is confident about all 10 of the new "Earth-like" planets found in their stars' habitable zones.Several of these planets orbit G dwarfs - the same species of star as our own sun.
