The bright gibbous moon appears near the Mars this morning as a prelude to tonight’s celestial encounter.

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.
Here is a daily summary about the planets during September.
May 28, 2021: This evening Mercury passes brilliant Venus for the second of three conjunctions during this evening apparition of the second planet from the sun. Use a binocular about 45 minutes after sunset to see the speedy planet 0.4° to the lower left of Venus. This is the closest visible conjunction until 2033.
May 24, 2021: Morning planets Jupiter and Saturn are in the southeast before sunrise. In the evening sky, brilliant Evening Star Venus, Mercury, and Mars line up along the solar system’s plane. The bright moon is in the southeast near Zubenelgenubi, “the southern claw.”
May 23, 2021: Five bright planets parade across the sky. Jupiter and Saturn are visible before sunrise in the southeastern sky. The star Fomalhaut is becoming visible below bright Jupiter and near the horizon. After sundown, Evening Star Venus, Mercury, and Mars are in the western sky.

Mars continues its eastward march in Gemini, but time is running out on its appearance as it approaches brighter evening twilight and a conjunction with Venus.
