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 ...

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 ...

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.

Scientists first suspected the existence of dark comets in a March 2016 study when they noted that the trajectory of asteroid 2003 RM had moved slightly from its expected orbit, which could not be ...

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.

Inner dark comets can be found within the inner solar system, which includes the planets Earth, Venus, Mars and Mercury, and move in nearly circular orbits around the sun.

NASA's discovery of seven new "dark comets" doubles the known population of these asteroid-like objects with cometary behavior. These dark, elusive bodies, some near Earth and others further out ...

The study's authors emphasize the need for further research on dark comets. Recent research suggests that the hazards presented to Earth by enigmatic objects known as "dark comets" may be higher ...

If you peer out into the space sharing Earth's general orbital vicinity around the Sun, you'll find a lot of rocks. We have counted, to date, more than 35,000 near-Earth objects: asteroids and comets ...

(CNN) — Astronomers have spotted seven new examples of a cosmic phenomenon known as dark comets that could help scientists determine whether the celestial bodies helped deliver vital elements ...

A reanalysis of the data from the "rubber-ducky" comet 67P, collected nearly a decade ago, suggests comets may have deposited a lot more water on Earth than scientists previously thought.
