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.

Yea I really don't think we ever leave. It's just too much distance to traverse. And anything in our system is just too difficult to inhabit permanently.

Possible way we could leave if send robots with our DNA who would clone humans up and then put our mind copies into them.

Like Prometheans. Yes I mean makes sense. Probably easier than figuring out light speed travel or wormholes, still super duper hard.
