The wind is no longer at Voyager’s back

"But now, after 33 years, that has changed: at 17 billion kilometers (10.6 billion miles) from the Sun, the spacecraft has reached the point where the solar wind has slowed to a stop. Literally, the wind is no longer at Voyager’s back."

This is a distance that is mind boggling. That is 515,151,515.1K a year; 1,410,407.98K a day; or just under 58,767K an hour. Thirty-three years at nearly sixty thousand kilometers an hour and we've barely left our own neighborhood.
