The moon will meet up with the Seven Sisters, the Pleiades star cluster, on Friday (Feb. 16), also displaying a rare optical feature on its surface that can be seen with telescopes.
The half-illuminated 7-day-old moon will be in its first quarter phase as it encounters the Pleiades star cluster, also known as Messier 45 (M45). During the meet-up, two lunar landscape features known as the Lunar X and Lunar V will be visible, named so because they resemble those letters of the alphabet. They both appear on the lunar surface near the dividing line between the light and dark sides of the moon's visible disk, known as the terminator line.
