Halley's comet was last visible from the Earth in the very early mornings of 1986. I was 15.0 years old at the time and never got around to seeing it. I have to wait until I am 90.6 to get another chance! The comet has a highly elliptical orbit and comes within 0.57 AU of the sun on its closest approach. What is the furthest the comet gets from the sun in AU? AU is the symbol for astronomical unit, and is the average distance between the sun and earth:1.49 x 10¹¹ m
