Formation of the Moon

Formation of the Moon

Scientists want to explain certain facts:

  • Orbit of the Moon
  • Composition of the Moon similar to Earth’s mantle (not crust or

core)

  • Features of the Moon like Aitken basin, craters and maria (of

basalt – cooled lava) Note: this is ongoing research as we explore and observe and collect data about the Moon.

Formation of the Moon

Main Theories:

  • Capture Theory – Moon formed elsewhere and was “captured” into orbit

by Earth

  • Fission Theory – Moon “split off” from Earth
  • Condensation Theory – Earth and Moon “condensed” out of the same

matter

  • Giant-Impact Theory – large body collided with Earth, ejecting the moon
