Elusive Planet Nine could be surrounded by hot moons, and that's how we'd find it

The mysterious Planet Nine may have up to 20 moons that could be superheated by the hypothetical planet's gravitational pull, making them easy to spot.

"Researchers think the trajectory of these ETNOs can be best explained by the gravitational force of an undiscovered mass. Based on these orbits, Planet Nine is likely between five and 10 times larger than Earth and orbits the sun from around 250 times farther away than our planet does. There have even been suggestions that the elusive object could be a mini black hole."

If we accept planet nine, the statement in the article shows it would be a super earth. Most super earth exoplanets orbit their stars much closer than 250 au distances, TRAPPIST-1 system an example. A super earth in our solar system can also create much chaos and instability too for planet Earth and the terrestrial planets in our solar system.

Here is an interesting simulation report on what could happen in our solar system if a super earth is orbiting around the Sun. What would happen if the solar system gained a super-Earth?, https://phys.org/news/2023-02-solar-gained-super-earth.html, ref - The Dynamical Consequences of a Super-Earth in the Solar System, https://arxiv.org/abs/2302.06641, 22-Feb-2023. “Placing the architecture of the Solar System within the broader context of planetary architectures is one of the primary topics of interest within planetary science. Exoplanet discoveries have revealed a large range of system architectures, many of which differ substantially from the Solar System model..." My observation. While the simulation uses 10^7 year timescale, the introduction of a super-earth to our solar system could create very chaotic conditions for our habitable earth and life on it. Good we do not have a super-earth or super-earths orbiting in our solar system. Using a 3-earth mass super-earth, a=3.0 au, e=0, P=5.1965E+00 years. In 1 Gyr this super earth could complete 1.9244E+08 revolutions around the Sun or about 192 million. The simulation report shows instabilities and chaotic conditions develop within 10^7 year time scale for various simulated conditions using super earths of different masses. Applying a 5-year orbital period, about 2 million revolutions take place and problems show up for our solar system, and inner terrestrial planets. Perhaps another fine-tuning problem concerning our origins is apparent, when comparing the solar system with other planetary configurations known today.

It might be real but beyond Pluto
