That's 16 days if the average speed is 20% lightspeed. In reality you need to speed up, and then when you're halfway there, slow down again.

Which raises the other question: how would we slow this thing down so it just doesn't keep going past the 900AU mark?

Regardless, I guess we would be fine picking a slower speed that would get it there in a few years, which might be significantly easier to achieve.

Breakthrough Starshot aims to do all that acceleration in 10 minutes.

It’s an ambitious project.
