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 far away from the Sun so it is a very hot 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.

Which of these stars (A, B, C) do you think has a habitable zone that is the farthest away? Why do you think this?

• I think Star A because it is the largest to the light and heat probably extend the farthest.

• I think Star B because it's in between sizes so it's just right. Just like the "Goldilocks" zone should be.

• I think Star C because it is the smallest and has the most energy. Smaller stars always produce more light and heat.

• I think they all have the same size of habitable zone.

5. Imagine someone says to you, “The Sun is not a star! It’s out in the daytime, and besides, stars are really tiny and dim. The Sun is big and bright.” What would you say to convince them that the Sun is actually a star?

• If the Sun was far away it would still appear the same size to us; therefore, it is a star.

• The Sun only appears big and bright because of how close it is to the Earth.

• It only appears bigger because it is the biggest star that is exists.
