The planets Saturn and Uranus will make a close approach, passing within 1°20' of each other.
From Cambridge , the pair will be visible between 22:49 and 01:37. They will become accessible at around 22:49, when they rise to an altitude of 21° above your southern horizon. They will reach their highest point in the sky at 00:13, 23° above your southern horizon. They will become inaccessible at around 01:37 when they sink below 21° above your southern horizon.
Saturn will be at mag 0.0; and Uranus will be at mag 5.6. Both objects will lie in the constellation Sagittarius.
They will be too widely separated to fit within the field of view of a telescope, but will be visible through a pair of binoculars.
At around the same time, the pair will also share the same right ascension – called a conjunction.
A graph of the angular separation between Saturn and Uranus around the time of closest approach is available here.
The positions of the pair at the moment of closest approach will be as follows:
| Object | Right Ascension | Declination | Constellation | Magnitude | Angular Size |
| Saturn | 17h54m50s | 22°18'S | Sagittarius | 0.0 | 18"3 |
| Uranus | 17h55m00s | 23°38'S | Sagittarius | 5.6 | 3"8 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 171° from the Sun, which is in Gemini at this time of year.
