Video of Possible Moon Outside Our Solar System (Artist's Interpretation)

About this video
Duration: 20 seconds

This is an artist's interpretation of the gas giant planet Kepler-1625b and a suspected accompanying moon. Estimated to be as big as the planet Neptune, the moon is unlike anything found inside our solar system. The planet and moon orbit the Sun-like star Kepler-1625, located 8,000 light-years away in the constellation Cygnus. NASA's Hubble and Kepler space telescopes uncovered tantalizing evidence for the moon's existence, but further confirming observations are needed. Hubble couldn’t photograph the moon because it is too far away. But its presence was deduced by watching how the moon blocks a little light from the star when it passes in front of it.
