If this comet is what we think is not like any item that humanity has ever seen

That’s what you will find out after reading this story:

  • 31 comet/Atlas is only the third interstellar object ever monitored by the solar system.

  • Although its origin is unclear, the comet is from the part of the Milky Way, which has been accommodated by some of the oldest stars of the galaxy.

  • Although his age was not confirmed if 31/Atlas actually appeared in the region, it could be 7 billion years (4.6 billion).


Little dishonest interstellar objects (ISO) entered our solar system. “Oumuamua almost stopped the Internet in 2017 when it crossed the past, and the Comet 2i/Borisov 2019. NASA Hubble Space Telescope was caught. Now we have another interlocutor.

Astronomers first watched 31/Atlas on July 1. Although its origin is still unknown, the researchers who seem to think that flying a piece of ice, dust and frozen gas came from the so -called milk knee thick disk. This ancient stars region – more than 10 billion years – is scattered above and below our galaxy thin disk (accommodated by younger stars).

If 31/Atlas is really born on a thick disk, it may be the oldest comet ever seen in a comet that has been around 7 billion years; It is 3 billion years older than the solar system. And the way it moves suspiciously up and down in the galaxy plane can show an object that comes from direct height and remains on the disk. If we were lucky, it could look at the early Milky Way from the inside.

It is believed that this comet was originally an icy planets, one of many smaller bodies that was once combined into planets. However, the way it has achieved today is more debatable.

“31/Atlas have physical differences compared to the first two detected ISO, but its orbit and the speed it receives as a member of the Galactic population ISO,” the researchers said in a study recently introduced by the Royal Astronomical Society in 2025. Arxiv;

The research team used the probability simulator, which model the stars trajectories, using the Satellite and Speed of Each Star, observed in 2014-2025. (Even dead) – about a billion stars. This made it with patterns of the chemistry and galaxy dynamics of the protoplanetary disc, allowing them to provide for the speed, age and chemical compositions of the bird road interstellar objects.

Experts can determine the characteristics of 31/Atlas, depending on which stars population it originated. Star systems, including our own solar system, are formed in protoplanetary gas and dust discs, and models assume that the characteristics of these discs are influenced by their stars. Models also suggest that Isa stops early from their stars and dissipates on the cold outer edges of the star system.

Another model used by researchers predicts how Isa’s speed is related to their age, composition and other qualities inherited from the star populations from which they originated. In this way, the team found out the preliminary age of 31/Atlas and that it is probably not the same star as the previous two intersections we have seen.

There are still 31 works of the atlas origin. It is unknown whether it took a relatively undisturbed road through space or had its own orbit of different stars. Despite what has been proposed so far, the comet is still covered with gas, dust and mystery. But since interstellar objects are believed to exist for almost indefinitely, they can carry particles from almost every star that has ever existed in a galaxy.

“ISO provides the opportunity to obtain evidence of the process of planets and evolution from many galaxy environments,” the researchers said. “Further observations of 31/Atlas will allow us to do this [test our] assumptions. “
