The bright gibbous moon – overexposed in the image above – that is over 90% illuminated this morning appears near the planet Mars.
This evening the moon appears close to the Red Planet as they rise into the sky around 10:30 p.m.
They appear together throughout the night as the lunar orb slowly moves away from Mars.
Farther east, Venus sparkles among the dim stars of Cancer. The Gemini Twins – Castor and Pollux – are to the upper left of Earth’s Twin Planet.
