We need not consider the eccentricity of its orbit, which, although relatively not very great, produces a variation of 50,000,000 miles in its distance from the sun, because, at its immense mean distance, this change would not be of much importance with regard to the planet's habitability or non-habitability.
But there were compensations. The importance of these "Northern lights" must not be overlooked in forming an opinion on the habitability of the far north in the "dark" winter months. The display was frequent and brilliant.
It was the discovery that the moon has no perceptible atmosphere that first seriously undermined the theory of its habitability. Yet, as was remarked in the introductory chapter, there has of late been some change of view concerning a lunar atmosphere; but the change has been not so much in the ascertained facts as in the way of looking at those facts.
The existence of this volcano in eruption, indisputably established by earthly savants, was favourable to the theory of the habitability of the moon. Barbicane became absorbed in reflection. He forgot himself in a mute reverie, filled with the mysterious destinies of the lunar world.
If the relative weight of bodies on the surfaces of planets formed the sole test of their habitability, Venus and Saturn would both rank with the earth as suitable abodes for men.
And though the former may seem to be straining at a gnat and swallowing a camel when he coolly tells you that violin and fiddle are the same word, while English care and Latin cura have nothing to do with each other, he is nevertheless no more indulging in guess-work than the astronomer who confesses his ignorance as to the habitability of Venus while asserting his knowledge of the existence of hydrogen in the atmosphere of Sirius.
Proctor wrote his Other Worlds than Ours and M. Flammarion his Pluralité des Mondes Habités, many most important and significant discoveries have been made that, in several notable instances, have completely altered the aspect in which the planets present themselves for our judgment as to their conditions of habitability.
"I regret," answered Michel Ardan, "not to know my honourable opponent personally. His objection has its value, but I think it may be combated with some success, like all those of which the habitability of worlds has been the object.
Coming to the question of life upon the asteroids, it seems clear that they must be excluded from the list of habitable worlds, whatever we may choose to think of the possible habitability of the original planet through whose destruction they may have come into existence.
The phenomenon was therefore adduced as an argument for the habitability of the planets by Gruithuisen, of the Munich Observatory, who, writing early in this century, suggested that the ashen light of Venus might be due to general illuminations in celebration by her inhabitants of some periodically recurring festivity, The materials for a flare-up on so grand a scale would, he thought, exist in abundance, as he conjectured the vegetation of our planetary neighbor to be more luxuriant than that of our Brazilian forests.
