My mind is fully blown that the SR-71 could outrun a comet
That’s like saying I can outrun a TGV (while it’s departing the train station)
Eh, I get the sentiment. Nothing in space comes to a stop and most speeds are well beyond human comprehension. The Earth orbits at 67,000mph, escape velocity is like 27,000mph, the ground at the equator moves at about 1,000mph, the Voyagers are in the 30k range, and the Park Solar probe peaks over 400,000mph. So to learn that a comet is a tangible aviation speed was neat to me, at least
The SR-71 could almost outrun the moon. Maybe it could. Claimed max 2,200mph vs average 2,288mph of the moon
