Overview
- Mars and Uranus reached a minimum separation of about 6 arcminutes during the predawn hours of July 4, 2026, with calculations placing closest approach near 5:00 UTC.
- The pair sat low in the east-northeast sky just below the Pleiades cluster, with Mars shining near magnitude 1.3 and Uranus at about magnitude 5.8.
- Because Uranus is near the naked-eye limit, observers were advised to find Mars first and then use binoculars, a small telescope, or smartphone imaging to confirm the faint, blue-green point beside it.
- Astronomers described the event as an appulse, meaning an apparent alignment only, and noted Jean Meeus as the source for the timing and separation; small-telescope users could also spot the nearby background star HIP 19146 about 2 arcminutes below Uranus.
- Coverage differs on how rare the pairing is going forward, with one outlet calling it the closest until 2053 and another saying a similar approach is not due until 2147, reflecting different criteria for what counts as a comparable event.
