Planetary Conjunctions for 2018


It is exciting to spot conjunctions in the sky, and the timetable below indicates there will be numerous opportunities during 2018. When two planets appear to be close in the sky, as seen from Earth, it is called a conjunction. They are not actually close, just as the stars in the sky are not close, but our vantage point on Earth makes them appear to be in the same area.

Click here to set your location and obtain more information about each conjunction event. You will have access to the conjunction timetable, position in sky, right ascension, declination, constellation, magnitude, and angular size of objects.

Conjunctions with the moon are also included in the table below. This information was obtained from In the Sky.org, which contains a wide variety of sky charts and timetables worth exploring.
