Habitability

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

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

• Yes

• No

How many stars have Earth-sized planets in their habitable zone?

• 15%

• 20%

• 25%

• 30%

Can planets be too big for life to exist?

• Yes

• No

How many of the 3 criteria for life does Kepler 452b meet?

• 3

• 2

• 1

• none

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 are big bright stars less likely to have habitable planets than smaller stars?

• they are too long lived

• they are short lived and run out of hydrogen fuel quickly

• they are too bright

• they do not produce enough heat

Why are very small stars less likely to have habitable planets than average sized stars (like our sun)?

• the habitable zones would be so close that planets would be tidally locked

• the habitable zones would be so close that planets would not orbit

• the habitable zones would be so far that the planets would be too cold

• the habitable zones would be very narrow, so it is unlikely any planets would be in it
