That is to say, they are aware that even in that infinitesimally small portion of the Universe of which we have any knowledge through the sense of sight, even when aided by the most powerful telescopes, there are millions of fixed stars—all of which are suns, equal in size to, and in some cases many times larger than the sun governing our particular planetary system. Each sun is a centre of energy for its planetary system. Our sun is the greater radiator of energy for our planetary system, which is composed of several planets known to science, and several still unknown to astronomers—our own planet, the Earth, being but one of a large family.
