Well, let's analyze what the VFX statement is saying:
I think "miles and miles away" is our biggest answer. Miles is plural, so that's at least two, and the addition of "and" gives it an estimated 2-4 miles of size.
This would easily put it above
S/2003 J 12, which is a natural satellite orbiting Jupiter. This moon has a radius of 1.2 kilometers, or a size of 0.7 miles. Its mass is
1.9×101e3 kg (Class T)
Since Nidavellir isn't a filled sphere, we'll assume 80% hollowness. That would be around
1.52e+13 kg (still Class T):
Applying
@ARCH0207's speed would put the mass at;
- F= 1.52e+13 kg * 768.67 m/s² = 1.19141439737559995e15 KGF (Class T+) (About 0.83x lower than the baseline for Class P)
And that's assuming the size of a Moon that's not even 1 mile while accounting for 80% hollowness, while applying the speed factor.
The final result should be 100% Class P, at least in my opinion.
