If the central body is the Earth, and the energy is only slightly larger than the potential energy at the surface of the Earth, then the orbit is elliptic with eccentricity close to 1 and one end of the ellipse just beyond the center of the Earth, and the other end just above the surface. Only a small part of the ellipse is applicable. If the horizontal speed is , then the periapsis distance is . The energy at the surface of the Earth c… WebJan 6, 2024 · Krag added that, on average, 100 to 200 tons of space junk re-enter the Earth's atmosphere in an uncontrolled way every year.
