B. the non-circular orbit of Earth around the Sun
C. the tilt of Earth's axis
D. the combined effect of the rotation of Earth and its orbit about the Sun

O What research question is the student investigating?
A. How long does it take Earth to rotate on its axis?
B. Does the moon rotate at a faster rate than Earth does?
C. How do the locations of the stars relate to the moon?
D. What is the relationship between time of day and seeing objects in
the sky?
The earth revolves around the sun in exactly 365 1/4 days which is equivalent to 1 year. To make up for the loss of 1/4 day, the calendar was adjusted so that we have a leap year for every 4 years. If the earth were to speed in its motion slightly so that a year would be completed in exactly 365 days and 6 hours, how often would we need to have a leap year?

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?
