Kepler-186f......
1. How far is Kepler-186f from earth?
2. What is a light year?
3. The Kepler spacecraft which discovered the planet, is unable to observe planets directly. How does Kepler identify details about a planet's existence? (Make sure you include specific, researched details.)
4. How big is Kepler-186f compared to Earth? Compare the diameter of Earth to Kepler-186f. 5. Scientists "speculate that such planets could be just as habitable as our own, but there would be differences." What do scientists suggest these differences might be? Make sure you include plant life in your answer.
6. What does astrophysicist, Sara Seager, from the Massachusetts Institute of Technology say about finding a close match to Earth? What does the James Webb Space Telescope have to do with the search for habitable worlds and how is Canada involved with the telescope?
7. What is your opinion about the discovery of Kepler-186f?

That is cool that they discovered it, I watched similar things like this before...(This is not my response)
1. How far is Keplar-186f from earth?
About 500 light years.
2. What is a light year?
9.4607 × 1012 km. Like about 6 trillion miles
There you go Mackenzie. My typo is fixed. I just want you to know that when you make a mistake I don't get annoyed.
Please fix Plz.
I know we are not supposed to post on this thing but isn't it that you can use any format for the Turkey Vulture thing?
You may choose the format for your response to the bird research.
For question 6, do we have to research who Sara Seager is, and what she said about Kepler?
Hi Eileen,
There is information about Sara Seager in the newspaper article. However, you may also do further research.
Thank you.
1. How far is Kepler-186f from earth?
About 500 light years away
2. What is a light year?
A light year is the distance you can achieve by travelling 1 year in the
speed of light, or 9,460,730,472,580.8 km.
3. The Kepler spacecraft which discovered the planet, is unable to observe planets directly. How does Kepler identify details about a planet's existence? (Make sure you include specific, researched details.)
The Kepler spacecraft discovers planets by detecting them once their orbits cross in front of their star, and it makes the star a tiny bit dimmer for a time, this is called the transit method.
4. How big is Kepler-186f compared to Earth? Compare the diameter of Earth to Kepler-186f.
The diameter of Kepler-16f is about 1.1 times the diameter of Earth.
5. Scientists "speculate that such planets could be just as habitable as our own, but there would be differences." What do scientists suggest these differences might be? Make sure you include plant life in your answer.
The scientists suggest that plant life might work differently on Kepler 186f and planets that have a red dwarf star as its sun because the light is infrared light, and plants may not be able to absorb that, most plants on earth only use optic light for photosynthesis. Even if they could process photosynthesis with infrared light, Kepler 186s light may not reach Kepler 186fs plants because red dwarfs are cool, small star.
6. What does astrophysicist, Sara Seager, from the Massachusetts Institute of Technology say about finding a close match to Earth? What does the James Webb Space Telescope have to do with the search for habitable worlds and how is Canada involved with the telescope?
Sara Seager said that while finding a close match to Earth is exciting, it is possible that life could emerge under a diversity of different conditions. The James Webb Telescope is a telescope that is very powerful telescope that is currently under planning and construction, it is planned to launch in 2018, it is used for observing in general, it can view planets and stars,and it uses infrared astronomy, which is very clear and can show better results than visible astronomy. Canada plays a big role in this, Canada is making the Fine Guidance Sensor for the telescope, as well as the slitless spectrograph.
7. What is your opinion about the discovery of Kepler-186f?
I think that is a great discovery, and gave NASA a lot of information about the red dwarf stars, since Kepler 186f was in a red dwarf’s solar system, they know that it might be possible that red dwarf stars have planets that are similar to earth. It is the first Earth-size planet
