Is the Oort Cloud Really at the Edge of Our Solar System?

The Odd Cloud is a region shrouded in mystery and speculation, where the Sun 's influence grows faint as it brushes up against the void of interstellar space.

If we've never directly observed it, how do we know it's out there? And why do some people question its existence? Join me today as we venture to the farthest reaches of our solar system.

The main region of the Kuiper Belt extends from Neptune 's orbit at 30 AU out to around 50 AU.

But recent evidence from NASA 's New Horizon spacecraft suggests a second region called the scattered disk, which continues to around 1000 AU.

It's with these key findings from observed comets that they didn't come from far out in space.

Odd cloud theory is that the odd cloud formed from ancient debris leftovers from when our planet formed 4.6 billion years ago .

After the planets formed, the surrounding area was still rich with these smaller leftover chunks of material called planetesimals.

Astronomers have never been able to directly observe the old cloud.

But with telescopes we can see stars far beyond our own solar system.

The old cloud is just too far and too dark for our telescopes to catch a glimpse.
