Oh darn- thought we had some real doom there for a second, but according to my calculations, in April 2026 that thing is still going to be well over 300,000 miles nominal distance from earth. They'll get a better clue once more observations are done over time. Too bad, I was ready to bring in my tomato plants, lock and load, and tell Intrepid what I really think of him. j/k.
Hey TA, not to nitpick... buuuuut....
92,955,807.267433 (1 AU) x .0000114246 (minimal approach in AU) = 1,061.9829157075 miles... let's just call it an even 1,062 miles on closest approach.
