I wouldn't get too excited. It may be the closest exoplanet to Earth, but at 4.23 light years it's still a LONG WAY away. To put in perspective, the current fastest man made object is the Juno Jupiter space probe, that has reached the astonishing speed of 165,000 mph (or 73.7 km per SECOND). Seems pretty fast, yeah? Unfortunately that's still only 0.00023 of the speed of light, so at that rate it would take 18,391 years to get there!
