Exoplanets- Easy

What does the term exoplanet mean?

• A planet with rings around it

• A planet with life on it

• A planet that orbits our sun

• A planet outside our solar system

How do scientists study exoplanets?

• By using telescopes on the ground and in space

• By sending space probes to explore them

• By traveling to the planets themselves

• By using satellites to observe them

What have scientists observed about exoplanets so far?

• There are more planets than stars

• There are no planets outside our solar system

• There are only a few exoplanets in the Milky Way

• There are no exoplanets with atmospheres

What kind of stars provide long-lasting stable conditions for life to take hold and evolve?

• Smaller, fainter stars like our sun

• Bigger, brighter stars

• Stars with powerful flares

• Stars with no radiation

Why are exoplanets super hard to see?

• Because they are too close to their stars

• Because they are too bright

• Because they are too far away and fainter than their stars

• Because they are too small

What can scientists infer about exoplanets from their size and mass?

• The temperature on their surfaces

• The number of moons they have

• The color of their atmospheres

• Their distance from their stars

What are some of the qualities that make a planet a place with the right conditions for life?

• Having a rocky surface

• Being at the right distance from their stars to have liquid water on the surface

• Having a thick atmosphere

• Being very close to their stars

When were the first exoplanets detected?

• In the 1980s

• In the 1990s

• In the 2000s

• In the 2010s

What are scientists doing to study exoplanets' atmospheres?

• Building observatories on the planets

• Using drones to fly through their atmospheres

• Sending astronauts to collect samples

• Making weather maps for some exoplanets

What have scientists found about the arrangement of exoplanet systems?

• They are arranged quite differently

• They are all arranged in the same way

• They are all arranged in a straight line

• They are all arranged like our solar system
