Nearly 2000 have been found so far. The most successful method is using transits, where a planet physically passes in front of its parent star, producing a measurable dip in the star’s light. Another is to measuring the Doppler shift in a star’s light due to reflexive motion as the planet orbits. Exoplanets appear to orbit nearly every kind of star, and we’ve even found planets that are the same size as Earth. We think there may be many billions of Earth-like planets in our galaxy. This is a reupload of last week's episode to correct an error in the way we covered reflexive motion. For more information on the change and reflexive motion, you can check out Phil's \u003ca href='http://www.slate.com/blogs/bad_astronomy/2015/08/07/crash_course_astronomy_exoplanets.html' target='_blank' rel='nofollow'\u003eblog\u003c/a\u003e -- Table of Contents Other Planets Orbit Other Stars 2:10 Nearly 2000 Have Been Found 9:29 Transits 5:44 Doppler Shift 3:30 Exoplanets Orbit Nearly Every Kind of Star 8:44 Billions of Earth-Like Planets 9:33 -- PBS Digital \u003ca href='http://youtube.com/pbsdigitalstudios' target='_blank' rel='nofollow'\u003eStudios\u003c/a\u003e Follow Phil on \u003ca href='https://twitter.com/badastronomer' target='_blank' rel='nofollow'\u003eTwitter\u003c/a\u003e Want to find Crash Course elsewhere on the internet? \u003ca href='http://www.facebook.com/YouTubeCrashCourse' target='_blank' rel='nofollow'\u003eFacebook -\u003c/a\u003e \u003ca href='http://www.twitter.com/TheCrashCourse' target='_blank' rel='nofollow'\u003eTwitter -\u003c/a\u003e \u003ca href='http://thecrashcourse.tumblr.com' target='_blank' rel='nofollow'\u003eTumblr -\u003c/a\u003e Support CrashCourse on \u003ca href='http://www.patreon.com/crashcourse' target='_blank' rel='nofollow'\u003ePatreon\u003c/a\u003e -- PHOTOS/VIDEOS Stars as viewed from \u003ca href='https://www.youtube.com/watch?v=TOQrx-7qgak' target='_blank' rel='nofollow'\u003eISS\u003c/a\u003e [credit: Alex Rivest \u0026 NASA] \u003ca href='http://www.nasa.gov/centers/goddard/multimedia/largest/Jupiter_sphere.jpg.html' target='_blank' rel='nofollow'\u003eJupiter\u003c/a\u003e [credit: NASA] \u003ca href='http://mars.jpl.nasa.gov/multimedia/images/?ImageID=2633' target='_blank' rel='nofollow'\u003eMars\u003c/a\u003e [credit: NASA/JPL-Caltech/MSSS] \u003ca href='http://solarsystem.nasa.gov/multimedia/display.cfm?Category=Planets\u0026IM_ID=7543' target='_blank' rel='nofollow'\u003eMercury\u003c/a\u003e [credit: NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of Washington] \u003ca href='https://www.nasa.gov/topics/earth/overview/index.html' target='_blank' rel='nofollow'\u003eEarth\u003c/a\u003e [credit: NASA] \u003ca href='http://photojournal.jpl.nasa.gov/catalog/PIA18182' target='_blank' rel='nofollow'\u003eUranus\u003c/a\u003e [credit: NASA/JPL-Caltech] Lost in the \u003ca href='http://planetquest.jpl.nasa.gov/video/23' target='_blank' rel='nofollow'\u003eGlare\u003c/a\u003e [credit: NASA Kepler Mission/Dana Berry] Reflexive Motion \u003ca href='http://spaceplace.nasa.gov/barycenter/en/' target='_blank' rel='nofollow'\u003egifs\u003c/a\u003e [credit: NASA] Artist's conception of PSR B1257+12's system of \u003ca href='https://en.wikipedia.org/wiki/Pulsar_planet#/media/File:Artist%27s_concept_of_PSR_B1257%2B12_system.jpg' target='_blank' rel='nofollow'\u003eplanets\u003c/a\u003e [credit: NASA/JPL-Caltech/R.
