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

Click For Summary
SUMMARY

Traveling at the speed of light, it takes approximately 7 to 12 hours to reach the edge of the Kuiper Belt, which is considered by some to be the boundary of the solar system, located between 55 to 80 astronomical units (AU) from the Sun. The Andromeda Galaxy, the furthest object visible to the naked eye from Earth, is approximately 2,500,000 light-years away. The discussion emphasizes the importance of defining the "edge of the solar system," as it varies based on different celestial bodies and their distances.

PREREQUISITES
  • Understanding of astronomical units (AU)
  • Familiarity with the concept of light-years (Ly)
  • Basic knowledge of the solar system's structure, including the Kuiper Belt
  • Awareness of celestial objects visible from Earth
NEXT STEPS
  • Research the distances of various celestial bodies within the solar system
  • Learn about the Kuiper Belt and its significance in solar system studies
  • Explore the concept of light speed and its implications in astronomy
  • Investigate the Andromeda Galaxy and its relevance to our understanding of the universe
USEFUL FOR

Astronomy enthusiasts, educators, students studying space science, and anyone interested in understanding the distances and structures of our solar system and beyond.

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?

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'.
