Habitable Zone

What is the band of potential habitability?

• the right distance from a star for an atmosphere to form

• the right distance from a star for a terrestrial planet to form

• the right distance and temperature for liquid water

• the right distance to protect a planet from the sun's UV rays

Compared to a smaller, cooler star, a giant hot star's habitable zone would be found _________________ .

• at a much greater distance

• at a much smaller distance

• at a much higher temperature

• at a much lower temperature

Why would planet E not be a good place to look for life?

• Too hot

• No oxygen

• Too cold

• No water

Look at the diagram above, which of the following would be the best planet to observe for life?

• E

• B

• C

• D

What determines where the habitable zone is located for each star?

• The star's distance from Earth

• The size of the star

• How many planets the star has

• The size of the planet

Any exoplanet in the black area inside of the green habitable zone is 

• too cold for life

• too hot for life

• just right for life 

Why do astronomers look for exoplanets in the green habitable zones? 

• those exoplanets could have liquid water

• they are the perfect distance away from their neighbors 

• the green represents the asteroid belts of the solar system.

If a planet is discovered to be in the habitable zone does that mean it has life?

• Yes

• No

What is the primary factor that defines the habitable zone around a star?

• The presence of an atmosphere

• The distance from the star where liquid water can exist

• The size of the planet

• The number of moons orbiting the planet

Which of the following statements is true about the habitable zone of a star?

• It is the same for all stars regardless of size or temperature

• It is closer to a star if the star is smaller and cooler

• It is further from a star if the star is smaller and cooler

• It is determined by the number of planets orbiting the star
