This is 632 megameters (million meters) per hour. The speed of light is 1.080,000 megameters per hour. So this object is traveling 0.58% of light speed.

edit:

0.058% of light speed. thanx modva

0.058%, but impressive nonetheless.

The other thing that's sort of impressive is it gives us an idea of the sheer scale of the speed of light. The fastest macro object we've ever created (I'm sure there's tiny things we've made and then gotten going really fast with a particle accelerator) can only go 0.058% of the speed of light. There's this speed limit of the universe at c, but it's so fast we can't even hit 0.1% of that speed limit.

It's wild to think that light is fast enough to circle the equator 7.5 times per second.

Lights fast wth slow down
