I don't understand this question at all. If you want to see the figure, let me know The figure below is a scaled representation of a planet's orbit with a semimajor axis of 1.528 AU. (Use the exact values you enter in previous answer(s) to make later calculation(s).)

Question

(a) Find the ratio of the aphelion-to-perihelion distance.
rA/rP=


(b) Find the perihelion and aphelion distances in astronomical units.
rP=( )AU
rA=( )AU


(c) Find the distance the Sun is from the center of the orbit.( )AU

Answer 1

this seems like part of a series of questions
... the note about values from previous answers

planetary orbits are elliptical, with the sun at one of the foci

perihelion is the closest approach to the sun
... distance from vertex to focus

aphelion is the farthest distance
... major axis minus perihelion

perihelion + aphelion = 2 * semimajor axis

you need the ellipse parameters; either from a previous question or measured from the "scaled figure"

Answer 2

a=1.5
b rP=1.22AU and rA=1.70AU
c=0.308AU
