La distanza di Proxima Centauri è di 4,22 anni luce (4×10¹³ km). L'Apollo 10 raggiunse la velocità record di 11 km/s. (vedi anche:Richard W. Orloff, APOLLO 10, The Fourth Mission: Testing the LM in Lunar Orbit, 18 May–26 May 1969, su Apollo by the Numbers, NASA, 27 settembre 2005. URL consultato il 2 maggio 2019.) Il viaggio di questa sonda sarebbe dunque completabile in: 4,0×10¹³ km/11000 km/s = 3,6×10¹² secondi (1,1×10⁵ anni).

la densità (ρ) è data dalla massa diviso il volume. Per il Sole pertanto la densità è:
