33rd in my “Exoplanet” series which explores facets of planets identified outside the solar system.

Kepler-186f is an Earth-sized exoplanet orbiting within the habitable zone of the red dwarf star Kepler-186. It is located about 580 light-years from Earth in the constellation of Cygnus. It was the first planet with a radius similar to Earth's to be discovered in the habitable zone of another star.

I don’t use AI tools to make my art. And AI tools do not have permission to train on or assimilate my art.

I have been using the same digital painting app to make art since 1999.
