Tunguska Explosion in 1908 skipped like a rock on a pond

Scientists now theorize that an iron-based asteroid over 600 ft. in size, skipped like a rock on a pond causing the Tunguska explosion that leveled 800 square miles of Siberian forest in June 1908.

The asteroid was traveling at 12 miles per second or 720 miles per minute. That means if the meteor had stayed aloft 4 minutes longer, it would have wiped out London.

My question is when can we expect this asteroid to complete its orbit and visit Earth again? Maybe next time, the rock won’t skip.
