Angles in Orbit
(point S on the diagram) on January 1, 2017. (Note: The planets’ distances from the sun are not to scale.) Reread “Moon Math.” In that article, you drew angles to complete the diagram of the Apollo 11 moon lander’s flight plan. Use what you learned to draw five more angles to see the position of the planets orbiting the sun Where Math Gets Real

1. On January 1, Mercury (point M ) and Venus made a 70º angle with the sun as the vertex. Draw this angle using point M on the innermost ring, which is Mercury. Label Venus as point V on the second ring. What’s the name of this angle? 2. Earth made a 19º angle with Mercury that lies in between the angle Mercury and Venus made. Draw this angle, labeling Earth as E on the third ring. What’s this angle’s name? 3. Mars was to the right of Venus, making a 33º angle with Venus and the sun. Draw this angle and label Mars as point R on the fourth ring. What’s this angle’s name?
4A. Mars and Jupiter made a 180º angle with the sun in the center. Draw this angle and label point J for Jupiter on the fifth ring.
4B. Uranus also makes a 180º angle with the sun and Jupiter, named ∠ JSU . Mark Uranus as point U on the seventh ring.
5. Neptune is marked on the diagram as point N . Saturn was between Neptune and Jupiter, making a 68º angle with Jupiter and the sun. Draw this angle, labeling Saturn as T on the sixth ring. What’s this angle’s name?
