The graph below shows how the brightness of a star changes over time due to the fact that it is orbited by an exoplanet. How does the exoplanet’s orbital period around its star compare to the orbital period of the Earth around the Sun?

Step 1

The orbital period of an exoplanet can be determined by taking the time difference(*Δt*) between two identical dips in the brightness vs time graph.

Let *t1* and *t2* represents the ...
