Question
Kepler's Laws: Using the orbit shown below and a ruler, measure the scale bar in the top left corner in centimeters. The length of the bar is equal to the distance in AU shown below the bar. Measure the aphelion and perihelion distance of the orbit in centimeters and convert to AU. (HINT: Remember, in your conversion centimeters should cancel and leave you with AU's)
b. Kepler's Laws: Find the semi-major axis by taking the average of the perihelion and aphelion distances
Period- 2.4149533 Years Scale 0.7707346 AUExplanation / Answer
Answer: a
The measured value of scale bar is 3 cm. And the distance measured of perihelion is equal to 4cm means 1.027648 AU and the value of aphelion 8.6cm means 2.2094432 AU.
Answer: b
1.6185456 AU is the semi major axis that is the average distance of measured perihelion and aphelion. (Calculated by adding the measured values of perihelion and aphelion and divided by 2)
