Neptune (March, 2018) ⬅︎
Neptune, the furthest known planet, is extremely dim and the most difficult planet to view. From a dark, moonless site, it may appear star-like in binoculars and as a pale blue-gray orb in a telescope. Although to see features or moons is unlikely, just to see this elusive, giant, distant world is special.

Being so far from the sun, Neptune moves slowly in our sky. Since its orbital period is 165 years, it takes about fourteen years to move through each constellation of the zodiac. So once you have found it, you won't have to look far to find it again.
