A deep- space staellite made primarily of aluminum is 10 m long when launched at 22 ⁰ C(72 ⁰F). The statllite eventually comes to thermal equilibrium with the cosmic microwave background temperature of -270.45 ⁰C (-455 ⁰F).

Assuming the satellite follows linear themal expansion, much will the staellite change leangth? ________ m which is _________ cm
