Question 1:

Which detection method relies on observing the periodic dimming of a star's light caused by a planet passing in front of it?

Explanation: The transit method relies on observing the periodic dimming of a star's light caused by a planet passing in front of it. This allows scientists to detect the presence of the planet and gather information about its size and orbit.

Question 2:

Which detection method measures the small shifts in a star's spectrum caused by the gravitational tug of an orbiting planet?

Explanation: The radial velocity method measures the small shifts in a star's spectrum caused by the gravitational tug of an orbiting planet. This method provides information about the planet's mass and orbit.

Question 3:

Which detection method relies on the gravitational bending of light from a distant star due to the presence of a massive object, such as a planet?

Explanation: The microlensing method relies on the gravitational bending of light from a distant star due to the presence of a massive object, such as a planet. This method can detect planets even if they do not pass in front of their host star.

Question 4:

Which detection method directly captures images of exoplanets using specialized instruments?

Explanation: The direct imaging method directly captures images of exoplanets using specialized instruments. This method is most effective for detecting large planets that are far from their host stars.

Question 5:

Which detection method relies on measuring the slight dimming of a star's light caused by a planet's reflection?

Explanation: The transit method relies on measuring the slight dimming of a star's light caused by a planet's reflection. By observing these periodic changes in brightness, scientists can infer the presence and characteristics of the exoplanet.
