Solve the below problem:
Q: Based on observations made during the 1996 sighting of the comet Hyakutake, it was concluded that the trajectory of the comet is a highly elongated ellipse for which the eccentricity is approximately e = 0.999887. Knowing that for the 1996 sighting the minimum distance between the comet and the sun was 0.230RE , where RE is the mean distance from the sun to the earth, determine the periodic time of the comet.
