At the speeds it travels, it might, on average, complete a revolution every 750 to 1,440 years. However, these speeds appear unstable, which makes it uncertain just how long it actually takes to finish a turn on its axis, Tkalcic said. It remains unknown exactly why these fluctuations in speed happen. green bay san francisco game play by play
