In the outer reaches of our solar system, far beyond the orbit of Pluto, lies Sedna, one of the most mysterious objects ever ...

Sedna will make its closest approach to the Sun in 2076, giving us a rare opportunity to visit the planetoid before it drifts ...

A team of researchers has outlined how a new "direct fusion drive" propulsion system could allow us to reach Sedna this ...

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 ...

Sedna has a highly eccentric and elongated orbit and is currently moving to its perihelion—the closest it gets to the Sun during its massive 11,400 years orbit. It will reach that point in 2073-74.

Sedna won't be back for over 10,000 years, and it may be the largest, most distant object that we'll have the chance to have a close encounter with until its return.

Sedna – a distant dwarf planet 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 2076.

Sedna was not the only object close to Pluto's size to be discovered in the early 2000s. Brown's team also found Quaoar, another dwarf planet candidate, and Eris.
