"An international team of astronomers have found the fastest spinning star ever discovered. The star, called VFTS 102, rotates at a dizzying 1 million miles per hour, or 100 times faster than our sun. It lies in a neighboring dwarf galaxy, about 160,000 light-years from Earth." - Google.

Huh?
"rotates at a dizzying 1 million miles per hour"
from

"The peculiarity of this star is its projected equatorial velocity of
~600 km/s (about 2.000.000 km/h), making it the fastest rotating massive
star known.[4] The resulting centrifugal force tends to flatten the
star; material can be lost in the loosely bound equatorial regions,
allowing for the formation of a disk."
"Astrometry Radial velocity (Rv) 228[3] km/s"
How many revolutions per day / hour / minute is that?
