Ten or twelve diame...Earth diameters.

from Daft Punk – Contact Lyrics on Rap Genius

Meaning

The diameter of the earth at the equator is 7,926.41 miles (12,756.32 kilometers).

So 10-12 earth diameters equals somewhere between 80,000-95,000 miles (127,000-152,000 km)

Granted the calculation is probably not relevant, since they’re almost certainly talking of angular diameter
