What is a key strength of the transit method for exoplanet detection?.
- A.It can detect planets at any distance from their star.
- B.It provides a direct measurement of a planet's mass.
- C.It allows for the detection of small planets around distant stars.
- D.It can determine the atmospheric composition of exoplanets.
Model answer
What a good answer should say
- It allows for the detection of small planets around distant stars.
Explanation
Why this works
The transit method involves observing the dip in brightness of a star as a planet passes in front of it. This method is particularly effective for detecting small planets, especially those that are far from their stars, as it can reveal periodic dimming that indicates the presence of a planet.
