Multiple choice

Which of the following is NOT a method used to detect exoplanets?

  1. Transit method

  2. Radial velocity method

  3. Microlensing

  4. Direct imaging
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Direct imaging is not a method used to detect exoplanets because it is extremely difficult to directly observe exoplanets due to their small size and distance from Earth.

Multiple choice

Microlensing is a method of detecting exoplanets that relies on the gravitational lensing effect of a massive object. When an exoplanet passes in front of a distant star, it can cause the star's light to be magnified. What is this magnification called?

  1. Microlensing

  2. Gravitational lensing

  3. Einstein ring

  4. Light amplification
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The magnification of a star's light caused by the gravitational lensing effect of an exoplanet is called microlensing.

Multiple choice

Direct imaging of exoplanets is extremely difficult due to their small size and distance from Earth. However, it is possible to directly image exoplanets that are relatively close to Earth and that are located in a region of space that is not too crowded with other stars. What is this region of space called?

  1. Habitable zone

  2. Goldilocks zone

  3. Circumstellar habitable zone

  4. Clear zone
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The region of space where it is possible to directly image exoplanets is called the clear zone.

Multiple choice

Which of the following is the most common method used to detect exoplanets?

  1. Transit method

  2. Radial velocity method

  3. Microlensing

  4. Direct imaging
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The transit method is the most common method used to detect exoplanets because it is relatively easy to use and can detect a wide range of exoplanet sizes.

Multiple choice
