How can I calculate this alien's AP?

[Oiguana2701]

Basically, I calculated this thing to be 1868866667.63 meters long, weigh 2.1489122e+29 kg and move at 23.3 times faster than light. Normally, I'd either use GPE or KE, but this is in space, so no gravity, and it's much faster than light, so no KE. It's also not a planet or moon or anything of the sort, as it's a giant manta ray, so no GBE. What could I do for this thing?

I assume you got the mass and speed from it's large size right?
