It is reported that Sirius is heading for the earth at a speed of 14.5 kilometers per second, and it is very likely that one day the earth will encounter the bad luck of "wolf coming". Of course, fortunately, none of you here can see that day.

Sirius is the brightest star in the whole day except the sun, but it is darker than Venus and Jupiter and brighter than Mars most of the time. It is about 8.6 light years away from the earth. At the speed of 14.5 kilometers per second, it takes about177,931year to reach the earth.
