How does a comet conect to the universe?

Answer 1

Like all visible matter, comets are 'just' part of the universe and do not directly 'connet' to it. Their most direct 'connection' is to their star. All comets orbit a star. But more specifically the ones we know about are a part of our solar system - that is, their orbits are controlled by their relationship with our Sun.

Some of them never go past our solar system's 'outer limits' - what is known as the heliopause - others do, and travel in what is generally considered as interstellar space, but they are still gravitationally tied to the Sun.

The greatest distance that Pluto goes from the Sun is less than 50 astronomical units (1 AU = the distance of the Earth from the Sun). Comet Hale-Bopp is believed to go as far as 370.8 AU - a truly staggering 55,000,000,000 kilometres from the Sun. It takes it 2533 years to complete 1 orbit, over 10 times the time it takes Pluto to complete an orbit.

Answer 2

Comets are icy bodies that orbit the Sun and are believed to be remnants from the early solar system. By studying comets, scientists can learn about the composition and history of the universe, as well as gain insights into the formation of our solar system. Comets are considered part of the celestial bodies that interact with the wider universe.
