WARNING: The following information is conjecture and not official information.
Assumptions: the moon is 2 km, and the NOVA bomb is only 5,000 km away.
Calc: Apply the Inverse Squared Law: Source Energy / (4 * Pi * R2) the radius is the distance from the source to the range.
x/ (4 * 3.14195... * 5,0002) = 4 Megatons per square kilometer to fragment a 2 km moon which requires 8 Megatons to be fragmented.
x = 1.2 Petatons.
Some may find this yield hard to believe for a fusion device, but the stated effects to the planet and nearby moon require explosive power of this magnitude. Whitcomb does mention, however, that the lithium triteride cases are compressed to "neutron star density" during the detonation, implying that the warheads themselves boost a second, much larger fusion reaction.
In Halo: Ghosts of Onyx, the detonation of the NOVA bomb was noted to have caused "300-kilometer-per-hour winds" to sweep over Joyous Exaultation. Using data from nuclear testing calculated for ideal shock fronts, if Joyous Exaultation had atmospheric pressures and elemental composition similar to that of Earth, a 300 kph wind velocity corresponds to a peak overpressure of 6 psi (31.4 kpa) and a peak dynamic pressure of 0.85 psi (5.9 kpa)
For comparative purposes, using the formula of yield equivalence for nuclear weapons, EMt = n * Y ^ (2/3), where "EMt" is the equivalent yield, "n" is the number of warheads, and "Y" is the actual yield of each individual weapon in megatons, the NOVA bomb has a yield equivalence of:
"Little Boy" - bomb dropped on Hiroshima, Japan; Yield = ~15 kilotons
(1,200,000,000 Mt ^ (2/3)) / (.015 Mt ^ (2/3)) = 18,566,355
18,566,355 Hiroshima-style fission bombs
or
"Tsar Bomba" - largest nuclear weapon ever tested; Yield = ~50 megatons
(1,200,000,000 Mt ^ (2/3)) / (50 Mt ^ (2/3)) = 83,203
83,203 Tsar Bomba thermonuclear bombs.
Fireball diameter - 217km
Blast radius - 6032 km
