Hitting a baseball hundreds of feet is incredibly hard. Accurately measuring those moonshots isn't much easier.

After Giancarlo Stanton decimated a baseball during the World Baseball Classic, MLB Network informed viewers that the hulking outfielder torpedoed the ball 424 feet at an exit velocity of 117.3 miles per hour. Statcast data, however, is still a relatively new tool.

ESPN's Home Run Tracker has also studied long balls since 2006, giving fans a better sense of how homers travel. Decades before these modern advances, historians were left to make questionable estimations or even use an actual tape measure.

So take any urban legends about someone's 600-foot homer with a grain of salt. As a result, no assortment of baseball's longest blasts can be considered 100 percent credible. With no concrete numbers for anything before 2006, evaluating all-time distances remains an inexact science.

But why argue over semantics when we can watch some of MLB's best sluggers sock a few dingers? Using the best information available, let's take a stab at locating the longest recorded home runs ever.
