Ultradense asteroids are superheavy
Asteroid 33 Polyhymnia is what’s known as a main belt asteroid. It orbits our sun between the planets Mars and Jupiter. Scientists have discovered that the density of this asteroid is much larger than that of typical matter. In different phrases, there’s nothing on Earth that compares with this asteroid’s ultradensity. So some scientists assume Polyhymnia and asteroids prefer it would possibly encompass superheavy components. These are components which are off the charts of the periodic table. On October 9, 2023, a press launch from the science writer Springer said that asteroids like Polyhymnia is perhaps:
… composed of unknown kinds of ‘ultradense’ matter that can not be studied by typical physics.
Superheavy! Cool …
Superheavy asteroids = CUDOs
Johann (Jan) Rafelski of the College of Arizona and two of his pupil co-workers based mostly their new examine on the concept of what they name CUDOs, or compact ultradense objects. These CUDOs are astronomical our bodies with a mass density larger than that of osmium. Osmium, with the atomic quantity 76, is the densest naturally occurring ingredient on Earth. There are greater atomic numbered components on Earth, they’re simply much less dense than osmium. The very best-numbered ingredient ever synthesized in a lab is oganesson, topping the periodic desk of the weather with atomic quantity 118.
Rafelski and colleagues suggest that asteroid Polyhymnia and people like it might be composed of components larger than atomic quantity 118. These are components nobody has ever noticed earlier than.
The European Bodily Journal Plus accepted the researchers’ peer-reviewed paper for publication on September 7, 2023.

Parts off the chart, however steady?
Physicists had already proposed what they name an island of nuclear stability of components with atomic numbers round 164. Rafelski and crew concentrated their new examine round this island and included extra unique kinds of ultra-dense materials.
By definition, superheavy components are these with an atomic quantity larger than 104. Parts with atomic numbers of 105 to 118 have solely been made experimentally and are unstable. Parts above atomic quantity 118 are solely within the realm of principle. However, typically, the density of the weather rises as you go additional down the chart, so scientists anticipate superheavy components to be extraordinarily dense.
Keep in mind osmium, the densest steady ingredient on the interval desk? Osmium has a density of twenty-two.59 grams per centimeter cubed (g/cm3). Scientists assume Polyhymnia has a density of round 75 g/cm3. So the crew was in search of steady, superheavy, ultradense components that might clarify Polyhymnia’s suspected composition.
Their calculations confirmed the prediction that atoms with round 164 protons of their nuclei (components with atomic numbers of round 164) had been prone to be steady. Additionally they discovered {that a} steady ingredient with atomic quantity 164 would have a density between 36.0 and 68.4 g/cm3. Whereas not a slam dunk, the vary does strategy the suspected density of Polyhymnia.
A goal for future miners?
If some asteroids within the asteroid belt actually do include components which are unobtainable on Earth, they could possibly be a future goal for mining missions. Rafelski mentioned:
All superheavy components – these which are extremely unstable in addition to these which are merely unobserved – have been lumped collectively as ‘unobtainium’. The concept a few of these is perhaps steady sufficient to be obtained from inside our solar system is an thrilling one.
