In theory, pressure from the sun's radiation could propel a spacecraft outward away from the sun. For a spacecraft of mass = 1340 kg at the same distance from the sun as Earth (150 million km), how much area would a 100% reflecting "sail" need to have in order to balance the sun's force of gravity acting on the spacecraft? For reference, the sun's intensity just outside Earth's atmosphere is 1400 W/m² and the sun's mass is 1,99 x 1030 kg, and the universal gravitational constant G = 6.67 x 10-11 Nm²/kg². Convert your answer to square km (1 km² = 106 m²). A = km²
