Assuming the Sun is a black body at a temperature of 6000 K and that the Earth is a black body calculate the equilibrium temperature of the Earth The angular diameter of the Sun is 10 2 radians Neglen sources of heat from the Earth itself If an opaque cloud of dust particles in the form of a spherical shell with a radius equal to half the radius of the Earth s orbit were interposed between Earth and Sun centred on the Sun calculate the equilibrium temperature of the cloud and the new equilibrium temperature of the Earth
