Why would it be difficult to live on Venus?
Venus is far away from the Sun so it is a very cold planet.
Venus is close to the Sun so it is a very hot planet.
Venus is close to the Sun so it is a very cold planet.
Venus is far away from the Sun so it is a very hot planet.
What is the “Goldilocks” zone?
A zone on the Earth where most people want to live.
A zone where planets get the right amount of heat and light for liquid water to exist
A zone in our Solar System where aliens live.
A zone in our Solar System where aliens live.
Which of these stars (A, B, C) do you think has a habitable zone that is the farthest away?
I think Star B has a habitable zone that is farthest away because it is in the middle and just right. Star B or C would be either too hot, or too cold. Star B is just bright enough, not too bright, nor too dim.
Star C is best because it is not too hot than the other stars. A is too big and too bright and too hot. It might be a little cold. We can just wear a lot of clothes or use technology to warm us up.
All planets are not ideal.
I think Star A has a habitable zone that is farthest away because it is bigger than Star B or Star C. Star A is probably brighter than Star B and Star C. So the lig

What is a Star?
Lots of Light
Air; Has no shape
A giant ball of gas in space that produces its own heat and light

The lifetime of a star depends on its:
temperature
absolute brightness
apparent brightness
mass
The Hertzsprung-Russell diagram shows that main-sequence stars:
increase in brightness as they increase in temperature
are mostly hot and dim
decrease in brightness as they increase in temperature
are mostly cool and bright
Characteristics used to classify stars include:
size, distance, and brightness
distance, size, and color
size, brightness, and temperature
color, brightness, and distance
What color are the coolest stars?
red
blue-white
orange
yellow
