2022 RM4 is categorized as a potentially hazardous asteroid because it is around 400 meters in diameter[3][a] and makes close approaches to Earth. It was discovered on 12 September 2022 when it was 0.61 AU (91 million km) from Earth and located at declination +65 near the northern circumpolar star Zeta Draconis.[1]
At 1 November 2022 18:26 UT it passed 0.01536 AU (2,298,000 km; 5.98 LD) from Earth.[2] As of 1 November 2022 the uncertainty in the close approach distance was ±77 km.[5] The asteroid should have brighten to about apparent magnitude 14.3 which is roughly the brightness of Pluto and was around 75 degrees from the Sun.[6] It may have been viewable by experienced amateur observers with a telescope that has an aperture of around 8-inches or better.[7]

By 2 November 2022 the asteroid was better placed for the southern hemisphere with a declination of –32.[6] Goldstone Solar System Radar using the Canberra Deep Space Communication Complex 70–meter Deep Space Station 43 and Australia Telescope Compact Array observed the asteroid on 2 November 2022.[9] It then came to perihelion (closest approach to the Sun) on 3 November 2022.[2]
