Pisa Sol flies into the Sun in seconds, which is actually her true form and really a machine the size of the Sun. Given that the Earth orbits the Regeneration Machine with no gravitational anomalies, I think it's safe to say she has the same size and mass as the Sun. On top of this? We can also see Pisa Sol and the planetary orbits on the screens.
Opening an ES Gate is also required to reach Pisa Sol in a short time period.
Ergo, she should be the same distance from the Earth to the Sun as the normal sun.The distance from the Sun to the Earth is
149,597,870km.
Timeframe is 8 seconds and 9 frames.
T = 1s/24
= 41.6666667ms X 9
= 0.375s + 8s
= 8.37500s
T = 149,597,870km/8.37500s
= 1.78624322e10/299792458
= 59.5826603 C
Final Results
Pisa Sol flies into "the Sun" = 59.583 C
