The period of an object in orbit around the Earth is given by the formula:
T = 2π√(r3 / GM),
where r is the sum of the radius of the Earth and the altitude of the satellite, G is the gravitational constant, and M is the mass of the Earth.
Plugging in the values, we get
T = 2π√((6,371 + 400)3 / GM) = 12 hours.
