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 12
A planet causes its host star to move in a small orbit. This movement is best detected by which method?
A planet is detected by observing a temporary increase in the brightness of a distant star. Which detection method is being used?
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 about the star?
Describe how the depth of a transit light curve relates to the size of an exoplanet.
Describe the main limitation of the direct imaging method for exoplanet detection.
Describe the main principle behind gravitational microlensing as a method for detecting exoplanets.
Explain the transit method for detecting exoplanets.
Explain why direct imaging of exoplanets is challenging.
Explain why the radial velocity method provides only a minimum mass for an exoplanet.
Explain why the transit method is more likely to detect planets that are close to their stars.
What is an exoplanet?
