Mysterious, nearly invisible objects known as "dark comets" may pose a bigger threat to Earth than scientists thought, new research suggests. These small, rapidly spinning objects wander near ...

A new study suggests that up to 60% of near-Earth objects are dark comets, a nearly invisible hybrid object that behaves like a comet and an asteroid at the same time.

A recent study suggested that nearly 60% of all near-Earth objects are dark comets that may have been a part of much larger bodies in the main asteroid belt, a region of the solar system that lies ...

Nearly invisible “dark comets” may have been responsible for bringing much of the water found on Earth to our planet ages ago. However, they could also pose a very terrible threat to Earth ...

Dark comets were first revealed in 2023, when a team led by Darryl Seligman of Cornell University identified six of them based on their anomalous motions.. Asteroids follow orbits dictated by the ...

Inner dark comets are smaller – typically 1,000 feet in size – and on circular orbits close to the Earth. Outer dark comets, shown in red, have longer orbits than inner dark comets, shown in gray.

In our study, we found seven new dark comets, bringing the total to 14. Now that we’ve found more dark comets, we’ve noticed that they come in two flavors. Outer dark comets are larger ...

The study examined seven dark comets and estimates that between 0.5 and 60% of all near-Earth objects could be dark comets, which do not have comae but do have nongravitational accelerations.

A strange class of space rock known as a "dark comet" has qualities of both asteroids and comets — and the hard-to-spot objects may pose a larger threat to Earth than we thought, according to ...
