On 16th August 2020, an asteroid (later called 2020 QG) has been recorded as the closest
asteroid (spotted so far) that flew by the Earth without colliding with it. At the nearest point
of approach, it was only 2 950 km above Earth’s surface and it had a velocity v = 12.3 km·s
−1
.
How much higher was its velocity compared to the escape velocity at that height above Earth’s
surface? Find the ratio v/vesc.
