  37. Definition of a Planet • Set in 2006 by the International Astronomical Union (IAU) states that in the Solar System a planet is a celestial body that: • is in orbit around the Sun, • has sufficient mass to assume hydrostatic equilibrium (a nearly round shape), and • has "cleared the neighbourhood" around its orbit.

  38. Kuiper Belt and Oort Cloud
