Which of the following is least reasonable regarding comets?
Group of answer choices
Short-period comets originate in the Kuiper belt and take less than than about 200 years to orbit the Sun.
Long-period comets originate in the Oort cloud and can take millions of years to orbit around the Sun, in randomly oriented orbital planes.
The ion tail of a comet tends to produce a blue glow, as the ions inside it absorb sunlight and re-emit the absorbed energy with a characteristic color (somewhat like the gas atoms in a neon light or in an Aurora).
An ion tail is typically narrow and straight and always trails the comet, like long hair in the wind.
The dust tail of a comet often looks curved and its whitish color is just reflected sunlight.
