Figure 2.3 demonstrates how the body is decelerated down in the atmosphere at
different angles of entry for a considered meteoroid. It can be seen that at the entry
angles of 7° and 9°, the body does not reach the dense layers of the atmosphere, and
either weakly slows down or does not lose speed at all.
It is interesting to study the movement of asteroids with the angles of entry into
the atmosphere located in the interval 7
◦
≤ θ e ≤ 10
◦ . At the angle θ e = 10
◦ due
to the shortness of the passage in the dense layers of the atmosphere, the meteoroid
does not have time to decelerate down significantly and falls to the Earth’s surface
at the 34th s with a huge velocity of 16 km/s. This leads to an explosion and an
almost instantaneous transition of kinetic energy of the meteoroid to mechanical and
