Show Giant Sun. Canopus, the giant of the solar system, sys-tem, is according to a recent calculation of Prof. W. F. A. Ellison, 49,000 times as bright as the sun. Its diameter Is 134 times that of the sun; it is 18,000 times larger in surface, 2,420,000 ' " times larger In volume. The distance of It from us, according to the same authority, is 489 light years. "Suppose," says Professor Ellis, "that, instead of being at this enormous enor-mous distance, it were placed in the center of the solar sytera, In lieu of the sun? It would then occupy eighty-, five hundredths of the space lying within the orbit of Venus, and, as seen from the earth, would subtend an angle of about 70 degrees of arc. Thus, when its lower limb was on our horl-i horl-i zon, its upper would be within 20 de- grees of the zenith. Needless to say, no life could exist on enrth with such i a neighborhood."
