Wow do scientists discover planets?
-They estimate that there is more than one exoplant for every star. There are over 1billion trillion starts in the observable unervrse
-The radial velocity method: fist planet found using this method in 1995.
-Planets pull slightly on stars creating blue or red waves depending on the direction. Jupiter rocks are sun around 12 meters per second.
Telescopes are another way that we find planets. The biggest telescope is the Gran Telescopio Canarias, Canary Islands, Spain, 2009

I found your question very interesting and it made me think of just how big the universe is. I liked how you showed the picture of the radial velocity method, it helped me understand how the method works. Overall I found your presentation very informative and interesting to listen to. Great job!
I liked the picture about radial velocity method and how you explained lots of detail. I wish you would have shown about how scientists can tell how far away the planet is.
