      Question #1: Asteroid Hitting the Moon

      • I was reading up on asteroid 2024 YR4, and I came across this on its Wikipedia page: ”Calculations using the observation arc of 55 days as of 18 February 2025 find that 2024 YR4 has a 1-in-32 (3.1%) chance of impacting Earth on 22 December 2032 around 14:02 UT and a smaller possibility of impacting the Moon about an hour later around 15:19 UT.” I know you’ve talked about this asteroid before and the potential consequences if it were to hit Earth – not great, not terrible. Given the timeframe, there would at least be some opportunity to evacuate affected areas. But what about the Moon? Since the Moon is much smaller, could a direct hit pose a greater risk of destabilizing Earth’s tides, for example? Is this something to be concerned about, and what kind of consequences might we expect if it actually happens? I’d love to hear your thoughts on this, and thanks for all the skeptical work you do! Best, Stefan Magnusson
