Web7 feb. 2016 · Explanation: Forgeting the Sun which is 1 AU from us, we have Proxima Centauri at 4.23 light-years from us. 4.23 light years is: 4.23year × 365 ⋅ 24 ⋅ 60 ⋅ 60 seconds y ear ×300000 km second. = 4.0 × 1013km. 1AU = 1.496 × 108km. So the distance of Proxima Centauri in AU is. = 4.0 ×1013 1.496 × 108. ≈ 267 thousand AU.
