Methods of Exoplanet Detection
This quiz covers the various methods used to detect exoplanets, or planets outside our solar system.
Questions
Which of the following is NOT a method used to detect exoplanets?
- Transit method
- Radial velocity method
- Microlensing
- Direct imaging
The transit method relies on the fact that when an exoplanet passes in front of its host star, it will cause a slight dip in the star's brightness. What is this dip called?
- Transit
- Eclipse
- Occultation
- Dimming
The radial velocity method relies on the fact that the gravitational pull of an exoplanet will cause its host star to wobble slightly. What is this wobble called?
- Radial velocity
- Doppler shift
- Orbital motion
- Stellar oscillation
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?
- Microlensing
- Gravitational lensing
- Einstein ring
- Light amplification
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?
- Habitable zone
- Goldilocks zone
- Circumstellar habitable zone
- Clear zone
