An exoplanet with a spin axis similar to Uranus's transits its star.If the exoplanet had large planetary rings,astronomers who measured the transit's depth might:
A) overestimate the planet's radius.
B) overestimate the planet's orbital semimajor axis.
C) underestimate the planet's mass.
D) underestimate the planet's orbital semimajor axis.

Quizplus · Accepted Answer

Large planetary rings would add additional transit depth, making the planet appear slightly larger than it actually is. Therefore, astronomers would overestimate the planet's radius.
