ASTER3 - Compute Megatons E per weapon required to boil and

vaporize an asteroid of specific diameter, using a two-weapon

shock-wave pincher. Each bomb uses 1/2 of the asteroid

vaporization energy 2E for an asteroid composed of iron pyrites.

The bombs are to be mounted firmly in the surface. The program

also gives the total stone asteroid catastrophic fragmentation energy

for shattering a stone asteroid to bits. For irregular

asteroids of volume V cubic meters, use d = 2*[(3V/4pi)**(1/3)].

Note that the gravitational binding energy of the asteroid

has been added to the total bomb energy and so escape velocity

has been added to the Fujiwara-Tsukamoto ejectae velocity.

Typical icy comet nucleus width < 10 km. Add binding energy for comets.

Asteroid impact energy based on 11.2 km/sec < v < 40 km/sec
