      No no, it’s Mercury, Venus, Mars, Jupiter, Saturn, The Sun, and The Moon. The seven planets, and days of the week.

        All planets have elliptical orbits just like periodic comets. Comets’ elliptic is just more extreme.

        Mercury, Mars and Venus have tails, they just aren’t as visible.

          While I understand they are all elliptical, isn’t that the reason they moved Pluto to a dwarf planet, because it’s orbit was “to elliptical” and crossing Neptune’s orbital path?

            Its orbit is also at a considerable angle relative to the plane all other planets orbit in. That alone made me question it’s planet-ness long before it got demoted. And I felt really validated when Jim Carrey’s kids in Me, Myself and Irene argued about Pluto being a planet or not.
