01 / This opposition
Saturn this year
This opposition is predicted for Oct 18, 2027, 00:31 (UTC), or Oct 18, 2027, 08:31 in Beijing (UTC+8). This is one geometric instant worldwide, when Saturn and the Sun differ by 180° in apparent geocentric ecliptic longitude; closest approach may occur at a slightly different time.
At this opposition Saturn is about 8.326 AU from Earth, with apparent magnitude -0.1 and a ring tilt of about 12.9°. A tilt near 0° presents the rings edge-on; appearance and observing conditions change at every opposition.

Predictions use Astronomy Engine and times are shown to the minute. They may differ from high-precision almanacs by a few minutes; future UTC also depends on uncertain Earth-rotation predictions.

The Beijing night sky at 22:00 that evening
Predicted sky: October 18, 2027 at 22:00 (UTC+8), Beijing (39.9042° N, 116.4074° E, elevation 43 m).
Saturn is about 47.2° above the horizon at azimuth 132.4°, measured clockwise from true north.
The chart uses the observatory’s ephemeris, real star catalog and constellation figures. Body markers are enlarged; this is a prediction, not a photograph.
The chart chooses a night-time view on the event date rather than the exact opposition instant, which may fall in local daylight. Changing the place or time changes the sky positions.
03 / Observing times in Beijing
From evening to the next morning
These are Beijing times (UTC+8) for the night shown in the chart. Events after midnight carry the next day’s date. For another location, set your observer position in the observatory.
- Saturn rises

- Choose a clear, dark period when Saturn is high. The weeks around opposition are good for observing too.
- Saturn is a bright point to the unaided eye. Use a small telescope for the rings, find it at low power, then increase magnification as atmospheric steadiness allows.
- The prediction does not model weather, buildings or light pollution. Faint planets marked on the chart may require optical aid.
