A total lunar eclipse will occur when the full moon and the nominal orbit of the moon line up together (The solution of two equations). From the following data algebraic equation for the phase of the moon and nominal orbit of the moon can be formed. A new moon (0%) was observed on December 17 and the full moon (10%) was observed on December 31 along with the nominal orbit of the moon (0%). The brimming orbit of the moon (100%) was observed on November 29. When the two equations are equal a lunar eclipse will occur. How many days from December 31 will next lunar eclipse occur? Given the coming year is a leap year - on what dates will the next 4 total lunar eclipses occur? Show the algebraic solution, any information you use.arrow_forward
