Proxima Centauri is about 4.2 light years from Earth.

  • About 4 x 1013 kilometers (40,000,000,000,000)
  • About 2.5 x 1013 miles (25,000,000,000,000)
  • About 265,606 AU
  • About 1.3008808 Parsecs

If the Earth was only an inch from the Sun, at the same scale, Proxima Centauri would be 4.2 miles away.

It is the closest star to us, after the Sun.
