20 C'eres is the largest asteriad in the Solar System. But witha mass of 9.38 x 10º kg, a radius of 469.13 km, and a maximum surface temperature of - 38.15°C it doesn't have enough gravity to keep an atmosphere.If the density of Ceres were to remain the same, what would its rodius need to be (in kilometers) for it5 escape velocity to the rms speed of Hydrogen gas (H,)ot its maximum surłace temperature?
