Traveling at c, how long to the edge of the solar system from earth?

Click For Summary

Discussion Overview

The discussion revolves around the time it would take to travel from Earth to the edge of the solar system at the speed of light, as well as the distance to the furthest observable objects in space. The scope includes conceptual exploration of astronomical distances and definitions of the solar system's boundaries.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions the time it would take to reach the edge of the solar system at light speed, noting the need for clarity on the distances involved.
  • Another participant suggests that the definition of the "edge of the solar system" is ambiguous and mentions the distance to Pluto and other bodies beyond it.
  • A third participant proposes that the edge of the Kuiper belt, located between 55 to 80 AU from the Sun, could be considered the solar system's boundary, estimating that light would take about 7 to 12 hours to reach this edge.
  • Additionally, the distance to the Andromeda galaxy is mentioned as approximately 2,500,000 light-years away, raising further questions about observable distances in space.

Areas of Agreement / Disagreement

Participants express differing views on how to define the edge of the solar system, indicating that multiple competing definitions and distances remain unresolved.

Contextual Notes

There is uncertainty regarding the exact distances to various boundaries of the solar system and the definitions used to describe them. The discussion does not resolve these ambiguities.

I was just wondering, how long would it take to travel from Earth to the edge of our solor system if we were traveling at the speed of light? and how long would it take to get from Earth to the furthest we can see into space at the moment?
 
Astronomy news on Phys.org
well for the answers to that, you got to know how long or far the solar sstem is first. i not very sure if any noe knows though...
but with the speed of light... it should not take that long.

Depends on what definition you have on "edge of solar system", you can google a bit about distance to pluto etc. But the solar system does not end with pluto, there are more bodies outside.

The most furthest object that we can see with a naked eye from Earth is the andromeda galaxy, approx 2 500 000 Ly away.
 
Like others have mentioned it depends on how one defines the edge of the solar system. i'd be tempted to say the edge of the Kuiper belt is the edge of the solar system, which is (arguably) 55-80 AU from the sun. 55 AU is the edge of the main body of the belt but there are other objects orbiting up to 80 AU away but they are fewer and further between. Using those distances it takes light about 7 - 12 hours to get from Earth to 'the edge'.
