Astrophysics Question-- When Jupiter aligns with Saturn to form...?

Question

When Jupiter aligns with Saturn to form a planetarian eclipse in which the light from the sun is blocked to at least half of either planet, what's the ratio of Jupiter land mass: Saturn visibility via sunlight?

Answer 1

huh?

an eclipse as seen from Saturn?  from Earth?  do you mean an occultation?

From Saturn, if Jupiter were close enough to the plane of Saturn's orbit to pass in front of the Sun, it would still be quit a small disc relatively.

Answer 2

ratio of landmass Jupiter: 1/2 landmass saturn

Answer 3

If Jupiter and Saturn were in line with the Sun, then looking from the direction of the Sun, Jupiter would appear large enough to completely hide Saturn. However, Jupiter's shadow isn't long enough to reach Saturn and from Saturn, Jupiter only appears about 1/5th of the Sun's diameter, so would appear as a black spot crossing the face of the Sun. Saturn can never block sunlight to Jupiter because Saturn is the more distant planet from the Sun.
