Saturn is at its best in September 2025. Here’s how to see it, and catch its meeting with the Moon

Saturn reaches opposition on 21 September 2025, rising to a peak altitude of 34° as seen from the centre of the UK.

On 8 September, it can be seen close to a 98%-lit waning gibbous Moon shortly after both objects rise and the sky darkens, at around 21:00 BST (20:00 UT).

Seeing Saturn’s rings

If you had a chance to catch a view of Saturn through a telescope in August month, you would have seen the rings were narrow but obvious.

At the start of August, the planet’s southern pole was tilted towards Earth by 3.4°, so they appeared like a thin elliptical band around the centre of the globe.

However, by 1 September, the tilt angle will have reduced to 2.5° and the rings will be noticeably harder to see again.

Saturn underwent a ring plane crossing back in March 2025, but at the time it was poorly placed for observation.

The next isn’t due until 2038, but between 11 November and 8 December this year, Saturn will appear to wobble to a very narrow tilt angle of just 0.4°.

Although not a true ring plane crossing, that is narrow enough to resemble a crossing through smaller scopes.

On 21 September, when Saturn reaches opposition, the tilt angle will be 1.8°. Such a narrow tilt continues to offer opportunities to see Titan and its shadow cross the planet’s globe.

At the end of September, Saturn remains at mag. +0.2 and, thanks to a slow westward drift, will have wandered across the border of Pisces back into neighbouring Aquarius.

Currently, Saturn and Neptune remain close to one another in the sky, lying 2.6° apart on opposition night, with Neptune located northeast of Saturn.
