What is the primary factor that makes shadows in the Kepler-47c system more complex than shadows in our own solar system?

The size of the planet Kepler-47c.

The distance of the planet from its stars.

The composition of the planet's atmosphere.

What fundamental condition is necessary for an eclipse to occur on a moon orbiting a planet?

The moon must be larger than its planet.

The planet must have a strong magnetic field.

An object must pass between a light source and the moon's surface.

The moon must be in the habitable zone of its star system.

In the Kepler-47 system, why would a total eclipse, where all starlight is blocked, be an extremely rare event on the moon of Kepler-47c?

The planet Kepler-47c is too small to cast a significant shadow.

The moon's orbit is too fast to stay in the shadow for long.

The two stars are far apart, so the shadow from one star is lit up by the other star.

The planet does not have a solid surface to reflect light.

Which statement provides the strongest evidence for the claim that *some* form of eclipse is possible on a moon orbiting Kepler-47c?

The moon is tidally locked to the planet.

The planet Kepler-47c is a large object and therefore must cast a shadow.

The two stars in the system are similar in size to our Sun.

The system is located within our own Milky Way galaxy.

Imagine the two stars in the Kepler-47 system were orbiting each other much more closely. How would this likely affect eclipses on Kepler-47c's moon?

Eclipses would become impossible because the stars would merge.

The duration of any eclipse would become significantly shorter.

Eclipses would only happen during the daytime on the moon.

Total eclipses would become more frequent because the two stars would act more like a single, combined light source, making it easier for the planet to block both at once.
