Scaling the width and height of the CT, and divide them to get the overall size of it.
The velocity was a tricky part. I did try to apply the velocity of a real world meteor when it enters the atomsphere to NV, except I calculated the distance between the CT and the ground, then divided by seconds.
It only takes about 29.6 Exatons to destroy the moon.
Velocity is consistent directed speed, while speed isn't.
There was no need to calculate each and every one of them. By calculating just one, you can assume the others are the same, since they're roughly same size. Also, read what I said to Apex.
Madara is underrated. Just wanted to spread the message.
