HW 2 (Chapters 3, 4)

Problem 3.5

Comet Halley has an eccentricity of 0.967 and a semimajor axis of 17.94 AU. What is the
sidereal period of Comet Halley? What is its distance to the Sun at perihelion? What is its
distance to the Sun at aphelion? The last passage of comet Halley by perihelion was in March
1986, when will we see Halley close to the Sun again?
GIVEN: Comet Halley has an eccentricity of 0.967

e = 0.967

Comet Halley has a semimajor axis of 17.94 AU

a = 17.94 AU

SOLUTION:
(a) What is the sidereal period of Comet Halley?
Solution: Here, sidereal period of Comet Halley: P =?
By Kepler's Third law, we have: Square of the period is equal to t...
