Exoplanets and Detection Methods starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Exoplanets and Detection Methods.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A star’s light dims by 1% every 10 days. What does this suggest about a possible exoplanet?
A star’s spectrum shows periodic red and blue shifts. What does this indicate?
Describe how the mass of an exoplanet can be estimated using the radial velocity method.
Describe one advantage and one disadvantage of the gravitational microlensing method.
Describe the main limitation of the transit method for detecting exoplanets.
A planet causes its star to move in a small circle as seen from Earth. Which detection method is being used? (1) Transit (2) Radial velocity (3) Astrometry (4) Direct imaging

Fill in the blank: The ________ effect is used in the radial velocity method to detect exoplanets.
Fill in the blank: The ________ method can detect exoplanets by measuring the tiny changes in a star’s position in the sky.
Fill in the blank: The ________ method can detect exoplanets by observing the gravitational lensing effect of a foreground star and its planet.
Fill in the blank: The ________ method is most effective for finding large planets close to their stars.
True or False: Direct imaging is easier for exoplanets that are far from their host stars.
True or False: Exoplanets can only be found around stars similar to the Sun.
True or False: Gravitational microlensing can detect exoplanets even if they do not orbit a star.
True or False: The astrometry method has detected more exoplanets than the transit method.
