I'm sure scientists would love to send a probe to the closest exoplanet, but the technology isn't even close yet. You mentioned a 10 lightyear visit, let's look at that;
Our current fastest space probe is Voyager 1 at 38,600 miles/hour. Let's say we figured out how to increase that by 50 times to 1,930,000 MPH. At that rate of speed our probe would take 3,469 years to make the 10LY journey, and then another 10 years for any information to start getting back to us. Our best bet is to continue to develope better and better ways to find and observe exoplanets.
