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
