The Large Magellanic Cloud streams through space at 378 kilometers per second, while the Small Magellanic Cloud moves at 302 km/see. Hubble even calculated the rate of this expansion, based on the observation of twenty-four galaxies, to be about 150 kilometers per second per million light-years of distance. If their paths cross Earth's orbit, they can strike our planet at speeds that average 20 kilometers per second (or 43,200 miles per hour). |
