A new class of exoplanets may exist in the neighborhood around supermassive black holes, with researchers proposing the existence of complex worlds known as ‘blankets’.
According to modeling by a Japanese research team, a safe zone exists around each supermassive black hole which could well be invaded by hundreds, if not thousands, of these black hole planets.
“Our results suggest that blankets may have formed around relatively low-brightness active galactic nuclei during their lifetime.” researchers write.
Keiichi Wada of Kagoshima University and his team suggest that these blankets be formed around newly arrived stars in the same way as planets: a vast cloud of gas collapses on its own, begins to spin, firing material out, and generating a disk of who then feeds it. Some of the materials fly further, eventually cooling and taking a steady orbit before forming planets.
A similar process can occur in the accumulation disk of a black hole, where larger batches of material grow larger and larger.

Eventually, such a pile goes deceptively after it grows large enough and collides with others, breaking away from the large gravity and reaching a point of relative stability, where it can cool down and form a planet (after about a million years or more).
Scientists even suggest that the formation of jerseys may be more efficient than their planetary counterparts, due to the heavy authoritarian weight of a supermassive black hole, which dwarfs that of a star.
Given that these are supermassive black holes, blankets will also dwarf their planet-formed planetary counterparts, as the mass involved is much larger.
Assuming a black hole of one million solar masses, approximately 13 light-years away, fans between 20 and 3,000 Earth masses could theoretically form in stable orbits.

We already know that black holes can reach up to 10 million solar masses, which would mean that, according to the Wada team hypothesis, at least some of these blankets could reach brown dwarf territory – not quite a gas giant and not enough star, but massively enough for them to fuse deuterium into their nuclei, stopping only the melting of hydrogen.
Because of the supermassive black hole distances and the weight they emit in their surroundings, we can’t actually detect any blankets (yet), so they will remain hypothetical for now, joining objects like the moons. of moons (moons of moons) and dusts (deceptive moons of large exoplanets boasting their orbits independent of their original host plans), which may exist but have not yet been found.
