  1. How do they work together to help life survive? The Planets Sun, Moon, Earth,

  2. What is a planet? • According to the IAU (International Astronomical Union) a planet must meet these three guidelines.

  3. What is a planet? • According to the IAU (International Astronomical Union) a planet must meet these three guidelines. • Is in orbit around the sun.

  4. What is a planet? • According to the IAU (International Astronomical Union) a planet must meet these three guidelines. • Is in orbit around the sun. • Has enough mass to maintain a nearly round shape.

  5. What is a planet? • According to the IAU (International Astronomical Union) a planet must meet these three guidelines. • Is in orbit around the sun. • Has enough mass to maintain a nearly round shape. • Called hydrostatic equilibrium.

  6. What is a planet? • According to the IAU (International Astronomical Union) a planet must meet these three guidelines. • Is in orbit around the sun. • Has enough mass to maintain a nearly round shape. • Called hydrostatic equilibrium. • Has cleared the neighborhood around its orbit.

  7. What is a planet? • Dwarf Planets:
