Homework 11 1. Two recent comets studied by the HST are Hale-Bopp and Hykutake. An observation about Hale-Bopp that particularly surprised astronomers was the activation of vents on the surface of the nucleus of the comet. A surprising observation of Hykutake involved the sight of three separate objects that seemed to have broken off from the nucleus; an occurrence that is not very typical of comets. 2. One of the asteroids studied by the HST is called Ceres, which is the largest of all known asteroids. Asteroids have a nearly round shape and a rocky inner core/thin, dusty outer crust. An asteroid is generally used to indicate a diverse group of small celestial bodies that drift in the solar system in orbit around the Sun. The asteroid rotates, much like the rotation of planets in our solar system. 3. Uranus is around 1.6 billion miles from Earth, at its closest point. Uranus does have a ring. Uranus also has an atmosphere, which is primarily made up of hydrogen, helium, and methane.
