Monthly sky – June 2025

Here are some details on the Moon’s phases, close approaches of planets and other astronomical events to watch for in the sky this June.

June 1: Conjunction – Close approach of Mars (mag: +1.20) southwest of the Moon (39%) early at night in a westerly direction in the constellation Leo.

June 10: Maximum Arietid meteor shower around 10:00 a.m. EDT. Unfortunately, the late rising of the constellation Aries (towards the end of the night on the 10th) and the presence of a full Moon will prevent us from fully enjoying the shower this year.
