Madara summons a massive asteroid from the upper atmosphere
The Calc[]
Method 1[]

- Onoki = 6px = 1.3m (official height)
- Rock formation = 334px = 72.3666666667m
- Top width (for future calcs) = 91px = 19.7166666667m

- Rock formation = between 1 and 2px (I'll assume 1.5 on average) = 72.3666666667m
- Meteor height = 322px = 15534.7111 meters
- Meteor diameter = 268px = 12929.5111111m
The meteor is a prolate spheroid.
- V = 4/3*pi*a^2*c
- V = 2.7195435e+12m^3
Rocky asteroids have a density between 3,000 and 5,000kg/m^3. The average'd then be 3,500kg/m^3.
- 2.7195435e+12*3500 = 9.5184023e+15kg
Using the average ablation value of 3,000m/s, since the meteor came from the upper layers of the Earth's atmosphere:
- 0.5*9.5184023e+15*3000^2 = 4.283281e+22 joules, or 10.237287284894838635 teratons of TNT (Country level)
Method 2[]
Based on this panel, we can scale the meteor's height and width by drawing the missing portion

- Pillar = 2px = 72.3666666667m
- Meteor height = 442px = 15993.0333333m
- Meteor diameter = 326px = 11795.7666667m
- V = 4/3*pi*5897.88333335^2*15993.0333333 = 2.3302998e+12m³
- M = 8.1560493e+15kg
- KE = 0.5*8.1560493e+15*3000^2 = 3.6702222e+22 joules, or 8 teratons of TNT (Country level)
