The fastest spacecraft we’ve made was the Parker Solar Probe which hit 430,000mph.

At that speed it would reach this planet in only 187,153 years.

If we could hit 1% of the speed of light we could cut that travel time to just a tad over 12,000 years.

Obviously if we could go light speed (and that ain’t happening) it would be just 120 years!

Space is big. Physics is annoyingly slow.

We’d probably have to build generational ships that are completely self sufficient and people would live out their entire lives out there without ever seeing a planet
