System travel calculation

How long to reach GJ 667 C?

This is the approximate distance from Earth to the host star system. Every listed planet in the system is effectively at the same interstellar distance for travel estimates.

At light speed23.6 years299,792 km/s

A physical reference only. A spacecraft with mass cannot reach light speed.

At 10% of light speed236 years29,979 km/s — hypothetical

No operational spacecraft can sustain this interstellar cruise speed.

At 1% of light speed2,360 years2,998 km/s — hypothetical

Still far beyond current spacecraft propulsion.

At Parker Solar Probe peak36,807 yearsAbout 692,000 km/h

Parker reaches this speed only very close to the Sun; it is not an interstellar cruise speed.

At New Horizons launch speed435,123 yearsAbout 58,536 km/h

A comparison using a real high-energy launch from Earth.

At Voyager 1 speed416,182 yearsAbout 61,200 km/h

A practical comparison with a spacecraft already moving into interstellar space.
