Proxima Centauri is about 4.24 light‑years away from Earth, which is roughly 40 trillion kilometers (around 4.0×10134.0\times 10^{13}4.0×1013 km).

Quick Scoop: How far is Proxima Centauri from Earth?

  • Distance in light‑years: ≈ 4.24 light‑years.
  • In kilometers: about 40,000,000,000,000 km (40 trillion km).
  • In astronomical units (AU): roughly 268,000–270,000 AU (1 AU = Earth–Sun distance).
  • It’s the closest known star to the Sun, part of the Alpha Centauri system.

To give a sense of scale: even traveling at the speed of the fastest current spacecraft, it would take tens of thousands of years to reach Proxima Centauri, which is why it’s a favorite target in discussions of future interstellar travel.
