At the beginning of The Last, as a warning sign of what is coming Toneri sends a small meteorite to Konoha that travels the distance between the Moon and Earth in a few seconds. From the minute 20:55 to 21:00, only five seconds is the time it takes for the meteorite to go from the Moon to the planet causing the friction to burn in the upper layers of the atmosphere.
Well, that same night the Kages met to notice that the Moon was approaching the planet in an unusual way, this means that the astronomers realized that the Moon passed the minimum distance to the one that is usually of the planet. Taking into account the minimum distance to which our Moon is usually as a base, that is 356500 km, and discarding a couple of thousand kilometers since it was just beginning to approach the planet, I believe that 350000 kilometers away sounds reasonable. Subtracting the height at which it enters the atmosphere and after being heated to incandescence by collisions with air molecules in the upper atmosphere, typically occurs in the mesosphere at altitudes from 76 to 100 km; so the final result is 349900 km.
The calculation is too simple the meteorite's speed is the time it took to get from the Moon to the planet:
Distance = 349900000 meters
Time = For the timeframe, this happens in 81 frames and the video runs at 24 frames per second, which gives a duration of 3,375 seconds.
Speed = 103674074 m/s or Mach 302256 (Relativistic - 0.34c)
This means an update to Toneri since he sent the meteorite at a relativistic attack speed. What is the importance of this feat? Well, it is a feat of Toneri before even implanting the Byakugan and evolve it into Tenseigan, plus we saw Toneri then do the same in his battle with Naruto using his Tenseigan Chakra Mode which implies that he should at least replicate such feat or overcome it with the pieces of Moon thrown at Naruto, who could dodge them without problems. This would be just one of the proofs that the characters of Naruto move at relativistic speeds, something that is literally a fact by feats and mentions but that people refuses to be accepted.
This feat would be applicable to the majority of characters God Tier of Naruto, since both Toneri doing the feat and Naruto later dodging were not at their maximum power (Naruto doesn't use his Six Paths Sage Mode his most powerful transformation against Toneri, and fight with him using about half of Kurama's chakra), that means that characters like Madara, Sasuke, Guy, Momoshiki, etc, would receive powerscaling and have a higher speed than this
