1 In a Thousand Year Chance To View NEA Naked
The latest on MN4 is that you will be able to see it with the naked eye on its 2029 close pass. MSNBC has an article on it, but their website seems to be down now and I can't get the link. An NEA as large as MN4 is expected to pass that close on an average of once every 1300 years. Recent radar observations refined orbit calculations which show an increase in potential impact probability, but a reduction in size estimate has left the palermo rating about steady.
