What is the axis of Comet?

Comets are part of the solar system because their axis is the Sun.

But their orbital path is not elliptical but

◆ parabolic parabolic and

◆ Hyperbolic is hyperbolic.

Just as there are two centers in the elliptical path of planets but the sun is always at one of these centers, similarly the comets of the same type of sun orbiting paths have the sun at any one center or axis.

Many comets originate from the Kuiper belt located beyond the planet Varuna, the Pluto-type Vamana planets also originate from here. Such comets are mostly parabolic circles.

● Beyond the Kuiper belt is the Oort cloud region, which differs in that it also orbits the Sun, its determination of the Sun's rotation period is uncertain.

Comets from this Oort cloud also come out of the Sun due to interstellar turbulence and are drawn towards the Sun, their Sun excursion path is hyperbolic - very circular, it will at times dissolve in the stellar region. Let's not come back. As you said that merges into deep space.

◆ The question may be that the planetary path is elliptical but why are comets etc. peri / hyperbolic?

लिए To find the answers to these, one has to go into the structure of the solar system, the galaxy to the solar system. The structure of the solar system has to go. These questions are related to each other which is called cosmology which is constantly searching.
