Suppose a friend is trying to claim that it is summer when Earth is closest to the Sun and winter when Earth is farthest away. Refute this claim in at least two different ways: (1) with an argument that invokes seasonal differences between the Northern and Southern Hemispheres and (2) with an argument based on the times of year at which Earth actually is closest to and farthest from the Sun. Write out your arguments clearly.arrow_forward

- 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_forward7arrow_forwardEach year, the radius of the moon’s orbit increases by about 3.8 cm.

Over the course of a night, suppose you are observing two stars that you label as Star A and Star B. The coordinates of Star A are RA = 9h 00m 0s, DEC = 0° 0' 0" and the coordinates of Star B are RA = 11h 20m 0s, DEC = 0° 0' 0". On that night, Star A passes through the zenith at 12:15 A.M. local time. At what time will Star B pass through the zenith? Explain your answer.arrow_forwardExplain the origin of the leap year.
