Saturn is about to make its closest approach to Earth, and that means you might be able to see its rings — if you have a telescope, that is.
Here’s what to look for this weekend.
When will Saturn be closest to Earth?
On Sunday, Sept. 21, one day before the official start of fall, Saturn will be at what’s called “opposition,” which in astronomical terms means the ringed planet will form a temporary line — the sun on one side and the Earth passing between them. Thanks to sunlight illuminating Saturn’s surface, it will appear exceptionally bright.
How close will Saturn get to Earth?
Earth’s outer planets are at their closest for the year during opposition, according to EarthSky. Saturn will be approximately 795 million miles (1.28 billion kilometers) away from Earth.
How big is Saturn compared to Earth?
Saturn is roughly nine times wider than Earth, writes NASA, with a diameter of about 74,897 miles. That means if Earth were the size of a nickel, Saturn would be as a big as a volleyball.
Where to spot Saturn in September 2025
Even if the weather doesn’t cooperate, Saturn should be visible all night in late September, writes EarthSky.
Saturn will rise in the east close to sunset. Look for the ringed planet in the constellation Pisces.
