What happens

In the first half-hour of their journey, the three travelers encounter a near-collision with an asteroid, which Barbicane identifies as a second, little-known satellite of Earth. They observe the moon with unprecedented clarity and look back at Earth, now a slender crescent. Barbicane suddenly wakes his companions to reveal why they did not hear the Columbiad's detonation: their projectile was traveling faster than sound.

Themes in this chapter

  • Scientific Exploration and Discovery

    Barbicane uses the asteroid encounter to calculate their exact distance from Earth, demonstrating applied astronomical knowledge.

  • The Sublime and the Unknown

    The travelers experience the awe of seeing the moon with incomparable purity and Earth as a fragile crescent, highlighting the vastness and mystery of space.

  • Human Audacity and Ingenuity

    The travelers' calm reasoning in the face of a potential collision and Barbicane's deduction about the speed of sound exemplify human courage and intellect.
