Evidence shows that there is another planet the size of Mars in our solar system

Our solar system has more surprises.

The eight official planets are not the only ones that survived the formation of our solar system, and Earth may have another sister planet lurking somewhere in interstellar space, in the “third zone” of the solar system, according to a recent article. published in the journal Annual review of astronomy and astrophysics.

This means that if Planet 9 is there, it could have a company the size of Mars.

Computer simulations hint at a twin the size of Mars beyond Neptune

The new study examines data from the mysterious third zone of the solar system and suggests that outside of Neptune there may be something the size of Mars lurking in the dark. Modern astronomy categorizes all known planets in our solar system into three types. You are one of the first, because the Earth is one of the four rocky inner planets which orbit the Sun within the main asteroid belt that separates Mars and Jupiter. The second group is the outer solar system and is also the kingdom of the gas giants Jupiter, Saturn, Uranus and Neptune. These inexpressibly large amounts of gas and ice accumulated around what scientists suspect are rocky nuclei.

But the third region of our solar system is beyond what we usually include in a casual conversation about the local planets. Outside of Neptune is the realm of dwarf planets such as Pluto, Sedna, Eris and even smaller bodies such as comets. But all this is wrong, according to researchers from a recent study. “Nature seems unlikely to have created four giant planetary nuclei, but then nothing larger than the dwarf planets in the outer solar system,” said Catherine Folk of the University of Arizona and Brett Gladman of the University of British Columbia in the study. To fully understand how the solar system came into being, scientists use computer simulations to see if special initial conditions or events can develop in a solar system like ours.

The hypothetical fraudster is not Planet 9

Many models that come closest to our real solar system start with at least one additional planet in a confusing position, according to Wolf and Gladman. These models suggest that the outer solar system has housed one or more rocky planets, about the size of Earth or Mars, in addition to the colossal gas and ice giants we now have. But over time, the interaction of these rocky wanderers with the huge gravitational fields of the gas giants pushed them into a distant orbit or even on an exit trajectory, far from the entire neighborhood. “I agree that it was probably originally Mars,” said planetary scientist David Nesvorny of the Southwestern Research Institute in a Back report. “[B]The question is whether he survived and whether we have evidence of that. “

“Our simulations have found that in about half of the cases of ‘simulated solar systems like ours,’ all the planets on the scale of Mars in the outer solar system have been ejected into interstellar space,” said astrophysicist Scott Tremain of the Institute for Advanced Study. Back report. “But in the other half, a ‘scammer’ planet was left in an orbit similar to that of the detached population of Kuiper Belt objects.” If this new deceptive planet exists, it will not be Planet 9, which is a much larger body that some scientists suspect exists even farther in space beyond Neptune. But while more modeling can help us determine where a scammer the size of Mars lurking, in the end the only proof will be: Let’s find him.
