Are there chances that the Moon might get knocked out of its orbit after the explosion?
Zero – people don’t realise just how huge the moon actually is. It’s approximately 3,500km in diameter and has a mass of 7.4×10^22 (that’s 74 with 21 zeros after it) kg. It would take a titanic collision to alter its orbit. Expecting the LCROSS spacecraft to alter the Moon’s orbit is like throwing a pea at a 10-ton truck and expecting the truck to be knocked off the road.
