Jules Verne,
Off on a Comet! a Journey through Planetary Space
“ If, in truth, a certain mass had been broken off from the terrestrial sphere, whither would it wend its way? What would be the measure of the eccentricity of its path? What would be its period round the sun? Might it not, like a comet, be carried away into the vast infinity of space? or, on the other hand, might it not be attracted to the great central source of light and heat, and be absorbed in it? Did its orbit correspond with the orbit of the ecliptic? and was there no chance of its ever uniting again with the globe, from which it had been torn off by so sudden and violent a disruption? ”
