In the frozen outskirts of the solar system, a reddish dwarf planet orbits in silence. Known as Sedna, it is so distant that one trip around the Sun takes more than 11,000 years. For much of that time ...

In a groundbreaking study recently published on the arXiv preprint server, researchers have proposed two innovative propulsion technologies that could enable humanity to reach the enigmatic world of ...

WASHINGTON - Strange planetoid Sedna, the most distant object in the solar system, was supposed to have a companion moon, but even the Hubble Space Telescope could not find it, scientists said ...

We know the planets close to the sun, and our closest neighbors, but few people know of the other big red hunk of matter orbiting the sun. The most distant known object in the solar system is Sedna, ...

Sedna is drifting into a part of its path where human technology can finally contemplate catching up, and that window will not reopen for roughly the span of recorded civilization. Its 11,400 year ...

Object 90377 Sedna — a distant trans-Neptunian object known best for its highly elliptical, 11,390-year-long orbit — is currently on its way towards perihelion (its closest approach to the Sun) in ...

The Kuiper Belt, the vast region at the edge of our solar system populated by countless icy objects, is a treasure trove of scientific discoveries. The detection and characterization of Kuiper Belt ...

When the distant planetoid Sedna was discovered on the outer edges of our solar system, it posed a puzzle to scientists. Sedna appeared to be spinning very slowly compared to most solar system objects ...

Our corner of the galaxy got a little stranger this week with the discovery of Sedna, the most distant object ever spotted in the solar system. Now astronomers are puzzling over how it got there.

“The Sun appears so small from that distance that you could completely block it out with the head of a pin,” said Dr. Mike Brown, California Institute of Technology, Pasadena, Calif., associate ...
