Three celestial bodies will be meeting up for one night in September in a cosmic party that should be widely visible in the sky, including in Kentucky.
The moon and Venus will soon be joined by the star Regulus for a brief rendezvous known as a conjunction, NASA said in a monthly skywatching guide. The upcoming close approach of the objects represents another opportunity for skygazers to see a conjunction soon after Venus and Jupiter shared a section of the night sky for much of August.
What makes the close approach of the objects so special this time around? Well, the moon-planet-star trio are among the brightest objects in our solar system, meaning the impending conjunction should be incredibly easy to spot for even the most amateur astronomers.
Here’s what to know about the Venus-moon-Regulus conjunction, and how to see the three bright objects this month.
What is a planetary conjunction?
A conjunction is an astronomical event in which at least two planets – or, in this case, other celestial bodies – appear to our vantage from Earth to be close together in the sky.
Even though the planets are in reality still tens of millions of miles apart, the events present a special opportunity for astronomers and casual stargazers to see multiple worlds in our solar system at one time.
So what causes conjunctions to take place?
As planets in our solar system orbit the sun at varying speeds, sometimes their orbital paths bring them close together on the same side of the sun. The same can be said of the moon, which instead orbits Earth.
When this event lines up with our view from Earth, we get a conjunction, according to the nonprofit Planetary Society.
When is Venus, moon, Regulus conjunction?
The waning crescent moon and the brilliant planet Venus appear close together in the dawn sky in this Nov. 9, 2023, photo made through an 8-inch telescope. The two bodies will pair up again at dawn on Sept. 19 when the bright star Regulus will also appear near them.
The upcoming conjunction will be a party between the moon – Earth’s only natural satellite – as well as Venus and a star named Regulus in the constellation Leo. The second planet from the sun, Venus is often referred to as Earth’s twin since both bodies are rocky and share a similar orbit.
The trio of celestial objects in conjunction should be visible Friday, Sept. 19, after sunset and before sunrise.

For those in the Northern Hemisphere, which includes the U.S., spotting the conjunction is as easy as locating the moon.
Look east in the early pre-dawn hours toward the waning crescent moon as it sets in the sky. The moon will be located near Venus and Regulus, Chelsea Gohd, a science communicator at NASA’s Jet Propulsion Laboratory in Southern California, explained in a video.

Do you need a telescope to see Venus, moon, Regulus conjunction?
While telescopes certainly will enhance the view, spectators don’t necessarily need any equipment to spot Venus, the moon and Regulus in the pre-dawn sky from the Northern Hemisphere.
That’s because after the sun, Venus and the moon are the two brightest objects in our night sky. Furthermore, Regulus is regarded as one of the brightest stars visible to Earth.
Seek out locations with unobstructed views of the horizons and check the weather forecast to ensure skies will be clear.
