See the moon and Jupiter enjoy their final meet-up of 2023 tonight

The moon will meet up with Jupiter, the solar system’s largest planet, for the last time in 2023 on Friday (Dec. 22) when the two celestial bodies make a close approach in the sky. Around the same time, the two celestial bodies will share the same right ascension, an arrangement astronomers call a conjunction.

The 10-day-old moon will be 86% illuminated during the close approach, with the lit lunar face currently growing as the moon heads to 2023’s final full moon, December’s Cold Moon, on Tuesday, Dec. 26.
