What marks the outer boundry of your solar system?

Answer 1

the ort cloud of comets

Answer 2

The point least distant from the Sun and its satellites (Planets, moons, asteroids,etc.) that is no longer controlled by the gravitational force of the Sun.

That is probably the outer edge of the Oort Cloud of comets.

Answer 3

This can be defined in at least two ways:

1) The "Heliopause". That's basically the limit of the "solar wind".

2) The outer edge of the "Oort cloud" of comets. That's the definition I prefer.

It's about half way to the nearest star besides our Sun.

Answer 4

There are several possible "correct" answers, depending on how you define "boundary". There is the "heliopause", the distance from the Sun where the solar "wind" is no longer detectable against the background gasses of the Milky Way galaxy. You might consider the Oort Cloud, the (theoretical, since we have no direct evidence of its existence) where comets drift in deep space until something disturbs them. You could say "the orbit of Neptune", the most distant planet.

But in a very real sense, there is no "boundary" of our solar system; our solar system exists within the Milky Way galaxy, and isn't really separate from it.

Answer 5

The outer boundary of the solar system is marked by the heliopause, which is where the Sun's solar wind is stopped by the interstellar medium. This is where the influence of the Sun transitions to that of the surrounding interstellar space.

Answer 6

The Oort Cloud at about a distance of 1 light year.

Answer 7

No one knows for sure.

Estimates place the edge of the Solar System at the boundary of the Sun's gravitational influence at about 2 light years or 125 million AU

Answer 8

The Oort Cloud of comets.

Answer 9

the ort cloud of comets
