On the evening of an autumnal equinox day Siddhant noticed that Mars was
exactly along the north-south meridian in his sky at the exact moment when the sun was
setting. In other words, the Sun and Mars subtended an angle of exactly 90° as measured
from the Earth. If the orbital radius of Mars is 1.52 au, What will be the approximate rise
time of the mars on the next autumnal equinox day?
Consider an imaginary planet in our solar system at an average distance of25 AU from the Sun.(a) Calculate the orbital period of this planet.
(b) This fictional planet has an orbital eccentricity of e = 0.4, calculatethe planet’s distance to the Sun at aphelion and perihelion.
(c) Another imaginary planet in our solar system has a perihelion distanceof 12 AU from the Sun and an aphelion distance of 68 AU. Is theeccentricity of this new planet greater or less than the planet in theprevious question?
Saturn has an angular size of 16”, and an observed Synodic Period of 1.035yrs. Saturn’s moon, Titan orbits the planet with an angular separation of 192”, with a period of 15.9days. From these observations we can determine Saturn’s mass.
Use the Sidereal Period of Saturn above to find the distance to Saturn from the Sun.
