As Universe Today explored in a previous post, it would take between 19,000 and 81,000 years for a spacecraft to reach Proxima Centauri using conventional propulsion (or those that are feasible using current technology)

Jesus, at 4.25 light-years.

Acceleration is a bitch. A manned flight would take longer as it would have to cap it's thrust to 1-1.5G or risk long term effects. Not to mention having to cancel ALLL of that thrust starting at the halfway point.

If you could maintain 1g of acceleration you would reach light speed in about a year.
