Question

A research team has discovered that a moon is circling a planet of our solar system: The moon
orbits the planet once every 7 hours on a nearly circular orbit in a distance R of 48000 km from
the centre of the planet. Unfortunately, the mass m of the moon is not known. Use Newton’s law
of gravitation with G = 6.67 · 10−11 m3
/(kg·s
