How far is the most distant star or object in our solar system

Question

in light years, earth years, and mileage.

Answer 1

This is unknown. Our universe is so vast and our telescopes can see up to a certain distance, we can't see the farthest thing in the universe.  What we do know is that the universe is expanding and the farthest thing in the universe, is getting farther.

Answer 2

On space websites so far the farthest known galaxies in our universe is 13 billion light years away. That means if you go at the speed of light which is 186,000 miles a second it would take you 13 billion years to get there. Now that is a very long way.

Oops I read your question wrong but I think the farthest object in our solar system  is the kuiper belt.

Answer 3

well, it depends on what you consider to be a part of the solar system.  By definition there are no other stars in our solar system (star=sun=solar), so that rules that out.

Some would say the most distant objects interacting with our sun are those of the oort cloud.  Others might say the outer boundaries of our system are defined by the heliosheath, which is the outermost part of the heliosphere.  After that you hit interstellar space.  The oort cloud lies outside of the heliosphere, so that's probably your best bet.  long-period comets are thought to originate from the oort cloud.  The edge of the Oort Cloud is about 50,000 AU = ~4.65x10^12 mi out from the sun (about 1 light year).  Earth years are a measure of time, not distance.

Answer 4

It is generally considered to be the heliopause, the area where outgoing particles from the sun meet incoming particles from the rest of space.  It is about 110 astronomical units from the sun.  (1 astronomical unit is about 93 million miles).
