The record for the longest home run in Major League Baseball is held by Babe Ruth, who hit a ball measured at an astounding 575 feet during a game in 1919. However, ongoing debates surround this record due to variations in measuring techniques. More recently, players like Giancarlo Stanton and Sammy Sosa have made headlines for their long homers, but none have officially surpassed Ruth's legendary distance. The fascination with long home runs adds to the dynamic nature of baseball and cultivates a sense of accomplishment among hitting specialists.
