REMARKS Earth's motion around the Sun was neglected; that requires using Earth's "sidereal" period
(about four minutes shorter). Notice that Earth's mass could be found by substituting the Moon's distance
and period into this form of Kepler's third law.
QUESTION If the satellite was placed in an orbit three times farther away, about how long would it
take to orbit the Earth once? Answer in days, rounding to one significant figure.
