Neptune February, 2018 ⬅︎
Neptune, the furthest known planet, is extremely dim and challenging 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. It will be in the Aquarius until 2022.
Viewing Neptune in February, 2018
LevelChallengingRatingBest ViewingEarly February, in evening
FindThe sun will be moving closer and closer to Neptune in earth's sky all month. So best viewing will be in early Feb. Look in Aquarius in the evening (see above). To find it, use a star chart or a GOTO telescope.
Although Neptune may be viewed in binoculars from a dark site as a dim 'star', a telescope is more likely to reveal it. Look for a pale blue-gray orb.
