Alien planet. Computer artwork based on observations by NASA's Spitzer Space Telescope of an alien planet thought to be just two-thirds the size of Earth - one of the smallest on record. This exoplanet candidate, known as , orbits a star called GJ 436, located just 33 light-years from Earth. The world orbits scorchingly close to its star, so in all likelihood this planet lacks an atmosphere and might even have a molten surface, as shown in this artist's impression.
