Ammonite: The TNO That Changes Everything

Money Explainers

The astonishing discovery of Ammonite forces us to rewrite the history of the outer solar system. What happened 4 billion years ago? Ammonite places new constraints on the search for Planet Nine and hints at a more dynamic past for our solar system. A must-see! One TNO can reveal so much. Ammonite is key to understanding the early solar system's gravitational complexity. #PlanetaryEvolution #Cosmos #SpaceScience #PlanetNine #Astronomy #ScientificBreakthrough

00:00The Ammonite Enigma. A more dynamic universe.

00:04A recent discovery is shaking up our understanding of the outer solar system.

00:09Ammonite, this newly found TNO, is a rare setenoid meaning.

00:13Its orbit is so far from the sun that Neptune's gravity barely influences it.

00:18What's astonishing is that while Ammonite's orbit appears stable for billions of years,

00:23it's substantially different from that of its setenoid companions.

00:26Numerical simulations reveal that all four known setenoids, including SEDNO itself,

00:32shared similar orbits approximately 4.2 billion years ago.

00:36This striking divergence, occurring about 400 million years after our solar system's birth,

00:41implies that something dramatic happened in the outer solar system,

00:45even imposing new restrictions on the potential location of the hypothetical planet 9

00:49and reducing its probability.

00:51The gravitational landscape of the early outer solar system must have been highly dynamic,

00:57possibly involving planetary migration or even the ejection of a large body.

01:02Ammonite opens a new window into understanding the solar system's past,

01:06revealing cosmic events still waiting to be uncovered.
