Unformatted text preview: motion where the Sun’s radial position relative to
a perfectly circular orbit is given by
ρ (t ) = AR sin(κ 0t )
Assume that the Sun is currently at the midpoint of its oscillation. Does your
result represent a minimum or a maximum estimate of the actual deviation?
HINT: You will need to determine which of the components of the Sun’s velocity
