اقتباس:A7. What results are expected from Kepler science?

To estimate possible results for the Kepler Mission science some assumptions must be made:

* One-hundred thousand main-sequence stars are monitored and variable stars are excluded;
* On average, two Earth-size or larger planets exist in the region between 0.5 and 1.5 AU. (An AU is an astronomical unit, the average distance from the Sun to the Earth.)
* About 0.5% of star-planet systems are aligned to allow transit observations of planets in or near the habitable zone of the star. (The habitable zone is the region where water can exist as a liquid on the surface of a planet.)

With those assumptions the number of detections still depends on what size planets are common. We may find

* About 50 planets if most are about 1.0 Earth radius in size
* About 185 planets if most are about 1.3 Earth radii in size
* About 640 planets if most are about 2.2 Earth radii in size
(Or possibly some combination of the above)
* About 12% of the cases with two or more planets per system

Most likely results will be some combination of the above. There will also be hundreds of giant planets found and many instances with two or more planets per system. For more on expected results see the Expected Results page.
