A few acknowledgements. When I first started reading about the Kepler mission, the Kepler website proved invaluable. It has a wealth of information, as well as some really good, pre-made and field-tested, material for educators. I’ve borrowed liberally from the Transit Tracks worksheet and Transit Tracks PowerPoint presentation, especiallyTransit Tracks Transit Tracks PowerPoint in some of the notes. I also used parts a nice lab, linked here, that covers much of the same material buthere that is suitable for a slightly more mature audience. I think that I’ve cited sources for all of the images as well as all of the information found in the notes (much of which were not used, but give a bit more information on the topics). If I’m missing a citation that you notice, please let me know.
TRANSIT GRAPHS AND EXTRASOLAR PLANETS HOPE CONCANNON TEACHING CONTEMPORARY MATHEMATICS CONFERENCE JANUARY 2014
EXTRASOLAR PLANETS ARE HARD TO DETECT BECAUSE THEY ARE SMALL, DIM, AND DISTANT
BROWN DWARF AND CHILD Spotted in 2004, the smaller red dot (the planet) is about 3 to 10 times more massive than Jupiter and is spinning around a brown dwarf, which is an object larger than a planet but without enough mass to ignite into a burning star. http://www.eso.org/public/news/eso0515/
THE FIRST DIRECTLY OBSERVED EXOPLANET Mass: eight times the mass of Jupiter Orbital radius: more than 300 AU Temperature: over 2700°F Credit: Gemini Observatory
THE KEPLER MISSION According to NASA, Kepler seeks evidence of Earth-size planets in the habitable zone of Sun-like stars. (Photo : Reuters) An artist's rendition of the Kepler satellite afloat in space.

WHAT IS THIS? http://eoimages.gsfc.nasa.gov/images/imagerecords/78000/78196/ISS031-E-089012.jpg
Which type of system will make it easier to find planets using transits? Small diameter planets or large diameter planets? Small mass planets or large mass planets? Planets close to their star or planets far from their star? Face-on orbits or edge-on orbits? Less massive stars or more massive stars? Planets with orbits that are closer to circular or highly elliptical orbits? Credit: NASA/Ames/Caltech.
TEMPERATURE OF THE PLANET Planet temperature can be determined from the parent star’s brightness and the planet’s size and orbital distance. http://discovery.nasa.gov/images/missions/kepler/PlanetTempAndSize.jpg
