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 10

Describe how the mass of an exoplanet can be estimated using the radial velocity method.
Describe how the presence of an exoplanet can cause a star to 'wobble'.
Describe one challenge of using the transit method to detect exoplanets.
Explain the radial velocity method for detecting exoplanets.
Explain why exoplanets are difficult to detect directly.

Fill in the blank: The _____ method can sometimes reveal the presence of exoplanet atmospheres by analyzing the starlight that passes through them during a transit.
Fill in the blank: The _____ method detects exoplanets by measuring the slight dimming of a star’s light when a planet passes in front of it.
Fill in the blank: The _____ method detects exoplanets by observing the gravitational effect of a planet on its parent star’s motion.
Fill in the blank: The _____ method is based on detecting the bending of light from a distant star due to the gravitational field of a planet.
True or False: Direct imaging is the easiest method for detecting exoplanets.
True or False: Exoplanets can only be detected if they are larger than Jupiter.
True or False: The astrometry method is commonly used to discover new exoplanets.
True or False: The discovery of exoplanets has changed our understanding of planetary systems.
