A comet that's bound to the sun and appears periodically is in an elliptical orbit.
A comet that whizzes through the solar system only once and then leaves
for good is in a hyperbolic orbit.
If the comet is periodic but with an exceptionally long period ... thousands
of years e.g. ... then we can't tell, from the small part of its orbit that we can
see, whether it's elliptical or hyperbolic.
False. While most comets orbit the Sun in the same direction as the planets (counterclockwise when viewed from above Earth's North Pole), there are exceptions. Some comets have retrograde orbits, meaning they orbit in the opposite direction of the planets.

No, comets are generally much smaller than planets. Comets are composed of ice, dust, and rocky materials and can range in size from a few hundred meters to tens of kilometers in diameter. In comparison, planets are much larger celestial bodies that orbit stars and have a defined spherical shape.
There are eight recognized planets in our solar system that orbit the Sun, along with their moons, dwarf planets, asteroids, comets, and other space debris. Overall, there are millions of objects that are known to orbit the Sun.
Comets.
comets crash into all planets!Planets don't have comets. Planets have moons. Comets orbit the sun
No. Comets are not moons as they orbit the sun, not planets.
False. While most comets orbit the Sun in the same direction as the planets (counterclockwise when viewed from above Earth's North Pole), there are exceptions. Some comets have retrograde orbits, meaning they orbit in the opposite direction of the planets.
Comets are made of ice (frozen water and gases) and dust that for some reason didn't get incorporated into planets when the solar system was formed. The shape of a comet's orbit is oval or egg shaped, the scientific term for it is elliptical.Read more about Comets by nineplanets.org

Yes.
Comets are small solar system bodies that orbit around the Sun. They are not planets because NASA said so.
No. Comets are much smaller than planets, are irregular in shape, and have highly eccentric orbits.
