A satellite of mass \( 1000 \, \text{kg} \) is launched to revolve around the earth in an orbit at a height of \( 270 \, \text{km} \) from the earth's surface. Kinetic energy of the satellite in this orbit is __________ \( \times 10^{10} \, \text{J} \).
(Mass of earth \( = 6 \times 10^{24} \, \text{kg} \) , Radius of earth \( = 6.4 \times 10^{6} \, \text{m} \) , Gravitational constant \( = 6.67 \times 10^{-11} \, \text{N m}^{2} \text{kg}^{-2} \) )
