A new planet-size object has been found! I’m sure you’ve heard about Pluto, the tiny planet at the edge of our solar system, so this strange object was found even farther. This could probably change what we thought we knew about space, as it usually happens with new space discoveries. For now, this discovery has been given the name of “Ammonite”, and it’s got astronomers rethinking big ideas, like whether there’s really a hidden Planet 9 out there. Doesn’t this discovery sound amazing? So, let’s find out more about this strange object.
A new object beyond Pluto
A group of scientists in Japan, from the National Astronomical Observatory, found a new object in space that is much farther than Pluto, the dwarf planet you probably know. This object was named 2023 KQ14, but for now, they call it “Ammonite” as a nickname while they wait for the International Astronomical Union to give it an official name.
How it was discovered
This object was discovered during the year 2023 thanks to a project called FOSSIL, which means “Formation of the Outer Solar System: An Icy Legacy.” To find it, they used a very large telescope called Subaru, which is on the island of Hawaii, in a place called Mauna Kea. Later, in July 2024, other scientists used another telescope in Canada, the Canada-France-Hawaii Telescope, and checked lots of data from different sources to follow its path and better understand its orbit. That’s how they discovered this object is a “sednoid.”
What is a sednoid?
“Sednoids” are objects in space that have very elongated orbits, like giant ovals, and they never come closer to the Sun than the planet Neptune, which is one of the farthest planets we know. A famous sednoid is the dwarf planet Sedna, and now “Ammonite” is part of this special group.
Implications for the Planet 9 Theory
What makes “Ammonite” so important is that its orbit does not match the orbits of the other sednoids we already knew about. This is interesting because until now, some scientists thought there was a very large planet called “Planet 9” far away, much farther than Pluto, that was affecting how these objects move with its gravity. But the fact that “Ammonite’s” orbit is different from the others makes the idea of “Planet 9” less likely.
Did a giant planet exist and get ejected?
Some scientists think that maybe there was a giant planet in the solar system, but over time it was pushed away and flew off into space, and that’s why we now see such strange and different orbits in these distant objects.
What it tells us about the past of the Solar System
Also, a scientist named Dr. Fumi Yoshida, who works at the Chiba Institute of Technology, said that finding objects with such long and distant orbits from the Sun means that something very special and strange happened a very long time ago, when objects like “Ammonite” were forming, at the beginnings of our solar system.
Waiting for an official Name
The International Astronomical Union is the one in charge of giving an official name to “Ammonite”. While we wait for the official name, this object is a reminder that space is full of mysteries that help us better understand our place in it. This is why scientific discoveries like this one are so important for the present time, so let’s hope scientists have the chance to keep researching about the unknown of space. Isn’t it amazing that every year we keep finding new things from the unknown of space, where almost no one has looked before?
