According to Lunar Laser Ranging experiment the average distance LM from the Earth to the Moon is approximately 3.92 x 105 km. The Moon orbits
the Earth and completes one revolution relative to the stars in approximately 27.5 days (a sidereal month).
Calculate mass of the Earth Me. Give the answer in 1024 kg.
Answer:

The earth moves about the sun in an elliptical orbit where angular momentum
about the sun is conserved. Earth's distance from the sun ranges from 0.983 AU
(at perihelion, the closest point) to 1.017 AU (at aphelion, the farthest point). The
AU is a unit of distance. If the orbital speed of Earth at aphelion is v, what is the
orbital speed of Earth at perihelion?
