Big Story: Found! Tiny Moon-Size Alien World Is the Smallest Exoplanet Two other known planets populate the Kepler-37 system. Kepler-37c has about three quarters the diameter of Earth and orbits ...

The planets are located in a system called Kepler-37, about 210 light-years from Earth in the constellation Lyra. The smallest planet, Kepler-37b, is slightly larger than our Moon, measuring about ...

The planet is about the size of the Earth’s moon. It is one of three planets orbiting a star designated Kepler-37 in the Cygnus-Lyra region of the Milky Way. The findings were published online on Feb.

Although Kepler 37-b has held the title of "smallest planet" for over a decade, it won't hold that designation forever. By most measures, Earth is small. The solar system's largest planet ...

Kepler-37 itself is the same class as the Sun, but cooler and smaller. All three planets orbit the star at a distance closer than Mercury is to the Sun. This makes them all very hot and inhospitable.

The next step, Barclay added, will be to look for Mercury-sized exoplanets at greater distances from the host star Kepler-37. More planets could be orbiting the star and await discovery.

This most recent discovery was made by NASA's Kepler mission, which is charged with identifying habitable Earth-sized planets. It brings the count of total known planets outside the solar system ...

NASA scientists have discovered a faraway planet that’s smaller than Mercury — far tinier than they expected they could find when they launched the Kepler space telescope nearly four years ago.
