See distant Neptune at its brightest in the night sky Sept. 19

Night sky September 2023

The ice giant Neptune will be at opposition on Tuesday (Sept. 19), meaning it will be in a straight line with our planet and the sun, with Earth in in the center.

The eighth and most distant planet from the sun, Neptune, will also make its closest approach to Earth, known as perigee, at around the same time. This means the distant planet will be at its largest and brightest in the sky tonight, making it an excellent time to locate and observe Neptune.
