Why is the transit method particularly effective for detecting exoplanets that are close to their stars?.
- A.They are larger and block more light.
- B.They have shorter orbital periods, leading to more frequent transits.
- C.They emit more radiation, making them easier to detect.
- D.They are more likely to have atmospheres that can be analyzed.
Model answer
What a good answer should say
- They have shorter orbital periods, leading to more frequent transits.
Explanation
Why this works
Exoplanets that are close to their stars have shorter orbital periods, which means they transit more frequently. This increases the chances of detecting them using the transit method.
