For what it’s worth, 120 miles is 20.4 light years.

Assuming current technolgy, a massive effort to build a nuclear-pulse engine and space craft(probably could be done in 10-15 years time, if we REALLY got after it) -— say by a benevolent dictator of USA that was really into space.

I bet a voyage would take 30 years one-way, our relativistic time, (5 years to accellerate, 5 to decellerate, 20 years or so at 3/4 speed of light).

Let’s go visit and find out.

Are those accurate numbers? Do we really have any technology which will continuously accelerate for 5 years at a given rate, with a mass low enough to let it peak at .75 SOL?

If so, I'd be interested in what it would cost to send a probe. I know ... it would take generations to get the data, but so what? I say we should have a look around if we can.
