According to the data of spectral analysis,universeIn a huge “Wandering planet“There is the presence of methane and water. Astronomers think it is a heavy metal object, and it is larger than Jupiter.
Scientists cannot determine the source of this mysterious object called CFBDSIR2149-0403.On the one hand, scientists feel that it is a young independentplanet, But on the other hand, it may also be a very low-quality brown dwarf (brown dwarf) with heavy metals.
When astronomers are searching for other planets, they often encounter some strange objects, and these objects always violate our knowledge of space.
The mysterious object called CFBDSIR2149-0403 is about 143 light-years away from Earth. It is also commonly referred to as a “giant free-floating planet.” It was first discovered by a team of French and Canadian astronomers in 2012, and it has aroused many discussions among scientists in this field.
According to the spectral analysis data, the object contains methane and water. In addition, astronomers say this is a highly metallic object, which is also larger than Jupiter.
Since its discovery, astronomers have thought of classifying it as one of the “wandering planets” because it is smaller than a brown dwarf. Brown dwarfs are approximately 13 times larger than Jupiter.
If we look at it from a specific point of view, from previous studies, astronomers have discovered that it is moving in the orbit of our galaxy together with other objects (Swordfish-AB). According to data, astronomers believe that the age of the object is between 50 million and 120 million years, but it is still young compared to the age of the universe. (Swordfish-AB is composed of thirty stars, and they will move together.)
But scientists have not been able to uniformly decide whether it is a “wandering planet.”
First of all, experts still haven’t found evidence that CFBDSIR2149-0403 is part of the solar system or was once part of the solar system.
Further research has determined that it moved alone, but this makes it more difficult for astronomers to determine its mass. Astronomers have observed the movement patterns of objects to confirm the above. Some astronomers even think it may be a high-quality brown dwarf.
Delorme said, “We are now officially overthrowing our initial assumptions and affirming that CFBDSIR2149-0403 is not a member of Swordfish-AB. This also removes our age limit for it. Although this improves us Understand it, but because we now need to consider the factor of its age, it has become more difficult to understand it.”
The most important conclusion of this new study is that CFBDSIR2149-0403 is likely to be one of the isolated planets less than 500 million years old, and has a mass of approximately two to 13 times that of Jupiter or a kind of age approximately. An ancient brown dwarf that is between 20 and 30 million years old, and has a mass of approximately two to forty times that of Jupiter.
In addition to the above two theories, some astronomers believe that these objects should not be classified as one of “wandering planets” or brown dwarfs, and we need to propose another new explanation. Countless questions are still unanswered.
We don’t know how CFBDSIR2149-0403 was formed. If it is a planet, then we have no idea how it reached its current position, because its current position is far from any other stars.
