Question
Halley's comet's travels around the sub in a highly elliptical orbit (e=0.967). It most recently passed through our neck of the woods in 1986,but it was not very bright, so you might have missed it. Fortunately, it will be back, although not until the year 2062.
1) What is the semi major axis of Halley's Comet's orbit in A.U.?
2) How close to the sun is Halley's Comet at perihelion (in A.U.)? Explain in detail the reasoning by which you obtained these answers, show all your work.
(Hint: To solve this problem you need both E and A. )
3) When Halley's Comet is furthest from the sun, it lies just beyond the orbit of which planet?
Explanation / Answer
Answer 1 -- The semi major axis of Halley's Comet's orbit 17.8 AU.
Answer 2 --- The most distant aphelion that Halley's comet gets from the sun is 35 A.U , one A.U is the approximate distance that earth is away from the sun which is approximately 150 million kilometres so , 35 A.U is 35 times earths distance from the sun . This is almost as far away as pluto is away from the sun . The closest Halley's comet gets from the sun perihelion is 0.57 A.U , so it gets closer to the sun than venus , the second closest planet to the sun
