In 2010, the Rosetta space probe passed within about 3,000 km from an asteroid known as Lutetia (the Latin name for the city of Paris). The shape of Lutetia can be approximated as spherical, with a diameter of about 100 km and density of 3,600 kg · m?³ . Assume that the mass m of Rosetta at the moment of the closest approach was 800 kg.
What was the magnitude of the force of gravity between Rosetta and Lutetia at the moment of the closest approach? Express your answer in Newtons.
A small disk of diameter D1 = 50 mm and emissivity e1 = 0.6 is maintained at a temperature of T1 = 900 K. The disk is covered with a hemispherical radiation shield of the same diameter and an emissivity of e2 = 0.02 (both sides).
