Exoplanets are tricky to find, so how do you go about finding them? MinutePhysics provides a clear and concise explanation on how to find an exoplanet, and it’s all to do with how much light the star darkens by when an exoplanet passes in front of it from our point of view.
The number of exoplanets has more than doubled in the past two years, with over 1800 being known to us today (compared to 786 in June 2012). I’m sure as our equipment gets more sensitive, we’ll be discovering even more in the years to come. Onwards!
