Lovely Crescent Moon

Venus, Mercury, Moon, March 2, 2025
Chart Caption – 2025, March 2: The crescent moon, Venus, and Mercury are in the western sky after sundown.

A lovely crescent moon is visible in the western sky after sunset.  Find it one-third of the way from the horizon to overhead, 30° above the west-southwest horizon.  The moon displays a phase that is 12% illuminated.

Earthshine

Crescent Moon with Earthshine
Photo Caption – 2024, June 10: Crescent Moon with Earthshine

Look for earthshine on the night portion of the moon.  This effect is reflected sunlight from Earth’s features that softly lights up the lunar night. Photograph it with a tripod-mounted camera or a camera phone, if held steadily, with exposures up to a few seconds.

Venus

Along with Earthshine, capture Venus and Mercury in the same scene.  Brilliant Venus is that bright star over 13° to the moon’s lower right.  The Evening Star is the brightest starlike body in the sky tonight. 

The planet was brightest about two weeks ago. Since then, it has dimmed slightly as it overtakes our planet.

Moving on an orbital path closer to the sun than Earth, it passes between our world and the sun on the 22nd.  Tonight, it is nearly 30 million miles from Earth, about 125 times the moon’s distance. 

Venus’ Phase Matches Moon’s Phase Tonight

Venus' Phases
Image Caption – Venus; phases

Through a telescope, Venus displays an evening crescent phase, 12% illuminated, that nearly matches the moon’s phase.  While the moon’s phase is waxing or increasing, Venus’ phase is shrinking.  The moon’s waxing and waning terms are not used with Venus, though their phases appear similar.

Mercury

Mercury can appear in this photographic scene with the moon with earthshine and brilliant Venus.  At 45 minutes after sundown, it is over 7° above the western horizon and 13° to Venus’ lower left. The speedy planet is visible to the unaided eye, though a binocular is helpful with its initial identification.

Jupiter in Nightly Planet Parade

Jupiter, Taurus, March 2, 2025
Chart Caption – 2025, March 2: Jupiter is high in the south-southwest, near Aldebaran, Taurus’ brightest star.

Mercury, Venus, and crescent moon are part of an evening parade of planets that includes bright Jupiter and Mars.  When looking for Mercury find the Jovian Giant high in the south-southwest, nearly 50° to the moon’s upper left.

Jupiter rambles eastward in front of Taurus, 5.6° above Aldebaran, the constellation’s brightest star.  It is generally moving toward the Bull’s horns, Elnath and Zeta Tauri.

Mars, March 2, 2025
Chart Caption – 2025, March 2: At 45 minutes after sunset, Mars is near Castor and Pollux, the Gemini Twins.

At this hour, Mars is over halfway up in the east-southeast near the Gemini Twins, Castor and Pollux.  The Red Planet marches eastward against the starry background, 7.0° to Pollux’s upper right and 7.4° to Castor’s lower right.

Mars passes Castor in a wide conjunction on the 21st, followed by Pollux’s conjunction 10 nights later.

Nightly Changes

Each night, the moon continues to wax.  A nice earthshine display continues for the next few evenings.  The bright four-planet parade continues for about another week as Mercury’s brightness fades and it retreats into brighter twilight.  Then Venus, Jupiter, and Mars are visible after sundown.

Venus is rapidly departing the evening sky.  It is easily visible for the next few weeks before inferior conjunction as it reappears in the morning sky before sunrise at month’s end. This leaves Jupiter and Mars as the bright evening planets.
