Ciel du mois - mai 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 May.

May 3: Conjunction – Coming together; Mars (mag: -2.01) south of the Moon (45%), early at night in a westerly direction in the constellation Cancer.

May 4: First quarter Moon – 9:52 a.m. EDT.

May 5: Conjunction – Coming together: Mars north of open cluster M44 (the Beehive) early in the night towards the west in the constellation Cancer.

Night of May 5 to 6: maximum meteor shower from the Eta Aquariids around 11:00 p.m. EDT. Unfortunately, the late rising of the constellation Pisces (at night’s end on May 6) and the presence of a Moon (70%) after first quarter will prevent us from fully enjoying the shower this year.

May 6: Equinox on Saturn at 2:09 a.m. EDT, the point at which the Sun will appear to cross the planet’s equator.

May 10: the Moon at its peak (97%) – furthest possible distance (406,700 km) from the Earth – at 8:46 p.m.

May 12: Full Moon – 12:55 p.m. EDT.

May 14: The Moon at aphelion (96%), its greatest distance from the Sun – 148,118,960 km – at 2:59 p.m. EDT.
