Here is an imaginary view of a planet-rise from a city on a faraway planet, known to earthly astronomers as Kepler-36c. It’s recently been found to be part of the closest two-planet system yet discovered. When the two worlds are closet, say the astronomers, the co-orbiting gas giant planet Kepler-36c would span three times more sky than a full moon does from Earth.
The distant exoplanet Kepler-36c – thought to be a gas giant world – is shown in this image as a NASA pic of Neptune.
The Seattle skyline pic is from Frank Melchior.
Eric Algol at University of Washington put this montage together.
Bottom line: Imaginary planetrise from a hypothetical city (really, Seattle) on faraway planet Kepler-36c. Astronomers believe that Kepler-36c and Kepler-36b constitute closest two-planet system yet found.
