Since Sunday's new moon, our closest neighbor in space has been moving east, away from the sun, and a very young wafer-thin crescent moon can be seen a half-hour after sunset just above the western horizon tonight. The thin waxing crescent will pass Venus for the last time this week during our sister planet's final days as an "evening star."
Look for Venus and the young wafer-thin crescent moon Tuesday evening, 10 degrees above the west-northwestern horizon and 45 minutes after sunset. Our sister planet, still a dazzling bright beacon, shining at --4.2 magnitude, will be sitting about 5 degrees to the upper right of the crescent. By Wednesday evening, the thin waxing crescent will climb about 15 degrees to the upper left of Venus.
The stunning pairing of Venus and the thin crescent moon may be enhanced if sky conditions permit you to see the dark disc of the moon faintly lighted by the reflection of sunlight off Earth.science - bookclub
