Breakthrough Starshot project is working towards accelerating a probe close to 20% of C. That's a significant fraction of C in these terms.

Even if we could get to .25 C, that would be 80 years for the probe to get there, and then 20 more for the data to come back.

But yes, that is still VERY close.
