  1. Terrestrial Planets Earth as a planet: interior & tectonics. Dynamics of the mantle Modeling terrestrial planets

  2. The Formation of the Earth • Precise timeline of early events using U/Pb and Hf/W isotope chronometers. Jacobsen (2003)

  3. The Formation of the Earth • Asteroid Itokawa might resemble the clumps that agglomerated to form the Earth & planets

  4. The Formation of the Moon Canup & Asphaug (2001)
