System travel calculation

How long to reach Kepler-1649?

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 speed301 years299,792 km/s

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

At 10% of light speed3,010 years29,979 km/s — hypothetical

No operational spacecraft can sustain this interstellar cruise speed.

At 1% of light speed30,100 years2,998 km/s — hypothetical

Still far beyond current spacecraft propulsion.

At Parker Solar Probe peak469,444 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 speed5.55 million yearsAbout 58,536 km/h

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

At Voyager 1 speed5.31 million yearsAbout 61,200 km/h

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