Close Approach of 2021 RW9? - PMSchu - 2025-09-27
SkyTools 4.1.11.18 Visual Pro predicts that this medium-sized, Apollo class NEO will make a close approach (to the nearest hour) on 2025 Oct 1 at 2200 EDT (Oct 2 0200 UT) at a distance of 0.03 AU traveling through Cassiopeia at 111"/minute. Peak brightness of 15.4 magnitude is predicted to occur on 2025 October 1 at ~1100 EDT (1500 UT) with 2025 RW9 traveling through Perseus at ~100"/minute and 0.03 AU distant, but in daylight in Columbus, Ohio. It's currently in Taurus at ~17 magnitude.
Neither CNEOS nor the MPC predict that 2021 RW9 will make a close approach this year, but the orbit's uncertainty is high, the Condition Code=9.
This might make an interesting challenge for Dennis.
