Studying Exoplanet Review Game

Why do scientists study exoplanets?

• 
  to make new technology

• 
  to search for ancient human artifacts

• 
  to find new places to vacation

• 
  to learn about how planets form and if life might exist there

Why might scientists compare exoplanets to Earth?

• to see if we can move them into our solar system

• 
  to expand the moon's influence

• 
  because all planets are similar

• 
  to understand if they could support life

Why do scientists use telescopes to look at exoplanets instead of traveling to them?

• 
  Traveling to them wouldn't give scientists as much information

• 
  Exoplanets are extremely far away

• 
  It's more fun to look at them through a telescope

• 
  Telescopes increase the colors of the exoplanets

What is the habitable zone around a star?

• the area of a galaxy with the most planets

• 
  the area where stars are born

• 
  the area where temperatures are just right

• 
  the area where planets are made of gas

Click on the planet that is most likely to be in the star's habitable (Goldilocks) zone?

• planet G

• planet D

• planet F

• planet H

If an exoplanet is too close to its star, what is one likely problem it could face?

• 
  permanent ice age

• 
  friendly aliens

• 
  frequent rain storms

• 
  extreme temperatures that could evaporate water

Match the exoplanet hazard with the best mitigation strategy.

• frequent planetquakes/ unstable terrain

• air filtration systems in shelters and suits

• toxic atmosphere

• solar-powered heating and cooling systems in shelters

• extreme temperature swings

• flexible buildings on shock-absorbing foundations

Do the exoplanets you studied have the features necessary for life? Why or why not?

• Yes, because they are close to Earth and have the same air and water.

• 
  Maybe, because some have the right conditions like water, but we still need more information.

• Yes, because scientists have already found aliens living there.

What is one feature scientists look for in an exoplanet to determine if it could support life?

• The number of moons it has

• 
  The color of the planet

• 
  The planet’s size and distance from its star
