What is the problem with seeing planets orbiting other stars?

• They are faint.

• They are hidden by the luminosity of their parent star.

• They are really far away.

• All of these answers are correct

The beauty of finding exoplanets with the transit method is that the amount of starlight blocked tells you ___

• how far away the planet is

• how big the planet is

• the density of the planet

• the mass of the planet

When a planet passes directly between an observer and the star it orbits, it blocks some of that star's light. For a moment this causes the dimming in the light of the star. This method is called...

• radial velocity

• gravitational microlensing

• direct imaging

• transit

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

• The exoplanet's distance from Earth

• The temperature of the star

• How many planets the star has

• The size of the planet

Which of the following is not a characteristic of a habitable planet?

• Earth-sized

• terrestrial planet

• Within its stars habitable zone

• gas giant

Why are big HOT 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
