Solar Eclipse Problem

Solar Eclipse Problem (a math problem, not about astronomy)

1. The problem statement, all variables and given/known data

To a good approximation, Earth and Jupiter move around the
Sun in circular orbits of 1.49 x 108 km and 7.79 x 109 km
radius, respectively. What is the maximum error that can
arise in the prediction of solar eclipse times (as observed from
Earth) on Jupiter caused by one of its moons if one fails to
take into account the variation of the relative position of the
two planets?

Answer: 2.6 x 103

2. Relevant equations

radius of earth: 6.37 x 103 km

3. The attempt at a solution

I think error happens when Earth and Jupiter are aligned. But the radius of Jupiter is not given. Please help!

Thanks!

hi sparkle123!

the solar eclipse means the moon of jupiter passing in front of the sun,

which we can tell from earth because we see the shadow of the moon passing across jupiter
