A large object called Sedna has been found past the orbit of Pluto. Parallax measurements from the Hubble Space telescope indicate Sedna is at a distance of 990 A. U. Calculations indicate its average distance from the Sun is 532 A. U., and its Perihelion is at 76 A. U. Based on this information, is this orbit highly eccentric, or not very eccentric? 7.) Based on the information given in question #6. What is the orbital period for Sedna?
