Now let's imagine what it would be like to try and figure out what's at the center of the solar system, if you lived on Jupiter. (Technically, you can't live on Jupiter, since it's made of gas and liquid, but let's pretend it had a solid surface you could stand on.) You and your fellow Jovians are trying to decide whether the Sun or Jupiter is at the center of the solar system. Someone suggests looking at Earth, to see how lit-up it can appear. Let's assume you have a telescope that can magnify Earth well enough to see any phases it might have. Would this work well, for trying to tell the difference between the heliocentric and Jupiter- centric models? Why or why not
