The Question:
How fast is the Moon traveling, using modern parameters?
The Answer:
The Moon’s actual distance from the center of the earth used by Newton was ft and the period is roughly 30 days, actually 27.3 days, or seconds (I asked Mr Google). The more modern value for this distances is ft, or billion feet or… feet.
So the speed is the distance around divided by the time to go around:
That’s about 2287 mph. Moving right along, that thing is. You’ll next be asked to do the same thing for a familiar orbiting object.
