Makes sense when thought about. So depending on the tilt of the ground track relative to distance from the equator, matching speed may be fun. Odd the article did not touch on that aspect.
You would just need to know the altitude of the plane, add to it the earth’s radius (approx 4,000 mi), then use the sum as “r” in the formula for a circumference: 2pi x r = C
I’m majorly confused. How does Mercury ( closet to sun) go from a toasty 800 degrees to several hundred degrees below zero in a 59 day rotation...... when Earth varies from 100 degrees to minus 30 or so in a 1 day rotation?
are they saying whenever the sun is not directly shining on a planet, it plunges into deep freeze? .....and because the Earth spins so quickly, the effect of not getting warmed by the sun during night is disapated by it’s quick spin?
