The Seager Equation calculator estimates the number of habitable planets in a set of stars based on a number of astronomical factors.
INSTRUCTIONS: Enter the following:
Habitable Planets (N): The calculator returns the number of habitable planets.
Theis a parallel version of the to estimate the number of habitable planets in the galaxy. Where the predicts the number of alien civilizations with radio technology, Seager has revised the to focus on simply the presence of any alien life detectable from Earth. The equation focuses on the search for planets with biosignature gases, gases produced by life that can accumulate in a planet atmosphere to levels that can be detected with remote space telescopes.
