How To See Comet Lemmon In Wyoming’s Night Sky

Another comet will soon come buzzing by Earth. Sorry, no aliens on board, just a comet.

Comet C/2025 A6. What a SEXY name.

Just call it Comet Lemmon. That's a more popular name that we can remember.

At the time I am writing this article, Lemmon is still far off, and we have cloudy skies over Wyoming.

That should all change by the time Lemmon gets close enough for us to see with the naked eye.

It will still be a good idea to at least use binoculars or some other visual aid.

To track the comet, for best viewing times, and to see where it is in the night sky, use this link. It's a really big sky in case you haven't noticed, so any aid you can find will help.

ALSO - download a night sky app on your phone. Some of them are free, and they will help you pinpoint where to look.

The video below will help you find a good app.

Lemmon is a non-periodic comet discovered by the Mount Lemmon Survey in images obtained on 3 January 2025. It has an inbound orbital period of about 1,350 years and will pass perihelion on 8 November 2025, when it will be 0.53 AU (Astronomical Units) from the Sun.

An astronomical unit (AU) is a unit of length equal to the average distance between the Earth and the Sun, defined as approximately 93 million miles or 150 million kilometers. 

Find a place that is free of light pollution. That's easy in Wyoming. Just head out away from any town where you have as much sky above you as possible.
