The “where” and “when” of the solar system Ceres Eris Quaoar Haumea - Planets between the Sun and Earth Only two: Mercury Venus In their orbits, where will we never see them? In their orbits, where is the best time to see them? The angle between the Sun and an inferior planet as seen from Earth At Maximum Elongation, the planet reflects the most amount of sunlight, appears at its brightest - Near the Sun at Sunset or Sunrise Ancients thought Venus was TWO different stars Evening Star Morning Star When the Earth, Sun, and a planet line up Inferior planets create two combinations: Inferior Conjunction Superior Conjunction Transit – when an inferior planet passes in front of the Sun Venus was in transit on June 5-6 2012!!! Why or why not? - Any planet orbiting beyond Earth Mars, Jupiter, Saturn, Uranus, Neptune When/Where are the best times to see them? The Earth, Sun, and a superior planet are in a line The Sun is in the middle The Earth, Sun, and a superior planet are in a line The Earth is in the middle Highest in the sky (peak location) Midnight (opposite the Sun!) “Take the orbits of any two planets and draw a line between the two planet positions every few days. Because the inner planet orbits faster than the outer planet, interesting patterns evolve. Each planetary pairing has its own unique dance rhythm. For example, the Earth-Venus dance returns to the original starting position after eight Earth years. Eight Earth years equals thirteen Venus years. Note that 8 and 13 are members of the Fibonacci number series. •Earth: 8 years * 365.256 days/year = 2,922.05 days •Venus: 13 years * 224.701 days/year = 2,921.11 days (ie. 99.9%) Watching the Earth-Venus dance for eight years creates this beautiful five-petal flower with the Sun at the center. (5 is another Fibonacci number.)” http://www.solarsystemscope.com/
