Possible extrasolar moon. Computer illustration of an extrasolar planet that may have the first moon (not shown) discovered outside the Solar System (exomoon). Observations using NASA's Hubble and Kepler space telescopes have provided evidence of what could be the first discovery of a moon orbiting a planet outside the Solar System. The moon lies around 8, 000 light-years from Earth in the constellation Cygnus. It orbits a gas giant planet (left), which in turn orbits the star Kepler-1625 (small, bright). | |
