Thanks, BMD. 2015 RN35 has a 'Rarity'=2 close approach according to the CNEOS website and 2010 XC10 has a 'Rarity'=3. 2018 YK2 isn't listed on the CNEOS website. Looking at the particulars for that NEO, JPL's Small Body Database Lookup website indicates a close approach on 2022-Dec-26 01:21 ± 4_13:23 UT at 0.04038 AU. The possible minimum separation is 0.00519 AU and the maximum separation is 0.08807 AU. That's using elements for 2022 Aug 9 00:00 UT.
It's probably worth keeping an eye on 2018 YK2 to see if the MPC gets better elements before the close approach occurs.
There's a recent discovery, 2022 UD9 that has a 'Rarity'=2 that makes a close approach on 2022-Dec-22 11:31 ± 00:16 UT at 0.01189 AU. I was waiting for the uncertainty to improve before posting about that one.
