Kepler-22b is more of Earth’s “cousin”, astrophysicist says
Astrophysicists and probably more than a few science writers are all abuzz about a new discovery. NASA has confirmed the first Earth-like planet outside of our solar system. And while Kepler-22b has been dubbed “Earth’s twin,” not everyone is ready to call for a family reunion. Dr.Jonathan McDowell,
anastrophysicist at the Harvard-Smithsonian Center for Astrophysics, believes Kepler-22b shouldn’t be called “Earth’s twin,” as it’s more of a cousin.
