No, he's not wrong.

The minimum earth distance you can achieve with the simulation is on 2023-03-25 20:00 UTC:
1.22e-3 au (183000 km)

(In fact, his video snapped it a little farther, not closer.)

'au' = astronomical units
'km' = kilometers

e-3 is scientific notation for shifting the decimal 3 places to the left.

So you have 0.00122 au
1 au = 149597870.70 km
1 km = 0.62137119 miles

Multiply those together, you get 113k miles...

Also the guy in the video doesn't seem to understand what the "condition code" means. He equated condition code 9 with "direct hit", but it's the opposite.

Hover your mouse over the label. It says "9" means maximal uncertainty.
It's now at 7, meaning the data is a little more certain.

That said, I can't find an error value for the minimum distance values,
so for all we know it COULD end up a hit.

It does seem weird to me that they delayed the solution so many days after the last observation.
It's up-to-date now (last obs. used == solution date).
