Suppose a space station is placed in orbit the same distance away from the sun as the earth but on the opposite side of the sun from the earth in a circumpolar orbit (the orbit plane is perpendicular to the plane of the earth's orbit around the sun). the average earth-sun distance is . an astronaut of mass on a space walk loses contact with the space station. the spacesuit has a cross sectional area of approximately . the mass of the sun is , and it emits radiation power at a rate . the gravitational constant is .
