Is it further to second base from the pitcher's mound than it is to home plate?

No. It is the exact same distance but it was shorter when they moved the mound back

The distance from home to the pitching rubber is 60 feet 6 inches. The distance from the pitching rubber to 2nd base is 66 feet 9 3/8 inches. The total distance from home to second is 127 feet 3 3/8 inches.
