The densest element on Earth can't compare. Asteroid 33 Polyhymnia might be what's called a compact ultradense object, or CUDO.

Some asteroids are dense. So dense in fact, that they may contain heavy elements outside of the periodic table, according to a new study on mass density. The team of physicists from The University ...

Properties, sources and uses of the element osmium. Osmium is one of the densest elements in the world. It is a lustrous, bluish white, hard metal and can be brittle even at a high temperature.

The two densest elements that have ever been measured are iridium and osmium. We know these have a density of 22.6 g/cm 2, but there are conflicting reports of which of the two is slightly heavier.

The densest, heaviest elements always sink to the core during planet formation, and gravitation compresses that core to be even denser than it would have been otherwise. But we don't have any such ...

Asteroid 33 Polyhymnia appears to be denser than the densest element in the Periodic Table. The densest naturally occurring element, Osmium, has 76 protons per atom. The asteroid could have more than ...

Study: Asteroid known as Polyhymnia may contain 'superheavy' elements unknown to humans The asteroid named 33 Polyhymnia is so dense that researchers at the University of Arizona theorize that it ...
