"It is a simple bolide, but one of such enormous dimensions that the Earth's attraction has made it a satellite."
"What!" cried Ardan, "another satellite besides the Moon? I hope there are no more of them!"
"They are pretty numerous," replied Barbican; "but they are so small and they move with such enormous velocity that they are very seldom seen. Petit, the Director of the Observatory of Toulouse, who these last years has devoted much time and care to the observation of bolides, has calculated that the very one we have just encountered moves with such astonishing swiftness that it accomplishes its revolution around the Earth in about 3 hours and 20 minutes!"
"Whew!" whistled Ardan, "where should we be now if it had struck us!"
"You don't mean to say, Barbican," observed M'Nicholl, "that Petit has seen this very one?"
"So it appears," replied Barbican.
"And do all astronomers admit its existence?" asked the Captain.
"Well, some of them have their doubts," replied Barbican—
"If the unbelievers had been here a minute or two ago," interrupted Ardan, "they would never express a doubt again."
"If Petit's calculation is right," continued Barbican, "I can even form a very good idea as to our distance from the Earth."
