- A total solar eclipse occurs when the Moon moves between the Earth and the Sun and completelyblocks out the Sun. This phenomenon is very spectacular and attracts people from all cultures.However, total solar eclipses can also take place on other planets of the Solar System.Determine for each of the following moons if they can create a total solar eclipse on their planetarrow_forwardthe earth is positioned between the sun and the moon in a nearly straight line.

- H3. A total lunar eclipse is observed on December 31. Predict the next lunar eclipse. 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_forward15.
