A rare celestial alignment is set to occur tonight, with the moon, Saturn, and Neptune rising together in the eastern sky for viewers in the U.S. The moon will rise before midnight, close enough to be seen together in a pair of binoculars. Saturn will appear above the horizon beneath the stars of the constellation Pisces, while Neptune will be visible approximately 1 degree to its upper left.
The alignment is caused by the moon’s proximity to Saturn and Neptune, with the planets’ relative positions allowing them to be observed together in the night sky. However, due to Neptune’s dim brightness (magnitude +7.8), it may not be possible to see without binoculars or a telescope.
For those interested in observing these celestial bodies, a pair of 10×50 binoculars will provide an ideal viewing experience. A larger telescope, such as one with a 6-inch aperture, can also reveal Saturn’s rings and variations in its cloud surface.
The alignment will remain visible throughout the night before Neptune and Saturn fade from sight in the southern sky by morning.
