Labroots recently shared key celestial events for November 2023 which offered skywatchers an opportunity to witness 16 days of events that included numerous meteor showers, comets, and planetary encounters. Now, Labroots wishes to share with you 22 days of celestial events for December 2023 that will ensure astronomy fans will not be disappointed. Each event is labeled in all caps for the type of event (e.g., MOON, PLANET, COMET, etc.) to provide skywatchers additional excitement to catch these incredible events!

December 1 (MOON and STAR): The Earth’s Moon will pass between 1–2 degrees from the star Pollux, which is located just under 34 light-years from Earth and resides within the constellation Gemini.

December 2 (MOON, STARS, and METEOR SHOWER): The Earth’s Moon will pass between 3–4 degrees from the Beehive Cluster, which is an open cluster of stars located approximately 577 light-years from Earth and is approximately 15 light-years in diameter. Additionally, the Phoenicids meteor shower will be at its peak with a variable number of observable meteors per hour.

Researchers are perplexed by the discovery of an exoplanet with a mass that greatly surpasses what would be predicted given its closeness to the parent star.
