September 2025 would first brighten under a supermoon on its third day in the seventh full moon. The greater moonshine does not only improve stargazing, but it also describes the ideal setting for the early autumn evenings.
Planets are Saturn, Neptune and Jupiter
The Moon comes back to make space with another cosmic encounter on September 8 by appearing alongside Saturn and Neptune. Later, it will meet with Jupiter on the 16th of the same month on that day, viewership by stargazers becomes phenomenal as two heavenly bodies would really close in their space.
Such close approaches are relatively easy to identify with the naked eye although telescopes provide more detail the rings of Saturn, Jupiter’s moons and the faint blue glow of Neptune.

Venus Will Shine Very Bright Near Regulus
Another exciting moment will be on September 19, when Venus will pass very close to Regulus and the brightest star in Leo. On that day, the Moon will also be with Venus, resulting in a lunar occultation when the Moon will briefly obscure the dazzling planet. This very rare event could make for an impressive celestial sight.
September also has two of the biggest oppositions that appear. On September 21, Saturn reaches opposition and where it becomes brighter and bigger in the night sky as Earth lies directly between it and the Sun. Next, on September 23, Neptune would follow and hence give astronomers a very great opportunity at observing this distant ice giant.

Day of Cosmic Confluence: New Moon, Eclipse and Equinox
September 21 is the exclusive day in the annals of astronomy as it also coincides with Saturn’s opposition, while at the same time there will be a New Moon and partial solar eclipse visible in some regions of the world.
Just one day later, on September 22, is the September equinox, marking the official change in seasons the beginning of autumn in the Northern Hemisphere and spring in the Southern Hemisphere.
Ending with Mars in the Limelight
The month will end with the Moon passing very close to it on September 24, further heightening an already spectacular celestial calendar.
With Mars glimmering an altogether reddish hue, it will contrast sharply with the silver glow of the Moon, making it a picture-perfect pairing in the night sky.
