Most scientists believe that Sedna is another planet, similar to Neptune. It is believed that the outer surface of Sedna consists of water, nitrogen ices, and methane.
Sedna is a dwarf planet. It is to far away to be one of plutos moons and is proved to orbit the sun
I believe they worship Sedna, the godess of the sea.
Not "a" Sedna; just "Sedna". Sedna is the Inuit goddess of the sea. Also, a dwarf planet named after this goddess.
Sedna
Sedna likely has a rocky core surrounded by a layer of water and ammonia compounds, followed by an outer layer of water ice. The exact composition and structure of its interior layers are still uncertain due to limited observational data.
Yes there are. As far as I can remember: Eris and Sedna Im sure more will follow.
No. Sedna is currently classified as a planetoid.
There is not a way to tell how many km are from the sun to Sedna. It is a long distence from the sun to Sedna.
Sedna is a small DWARF planet made of ice and rock.
Sedna does not have any moons. It is a planetoid located in the outer reaches of the Solar System beyond the Kuiper Belt.
Sedna is not a moon of Saturn. It is a dwarf planet that is located in the outer parts of the Solar System. Sedna was discovered in 2003.
Sedna is a trans-Neptunian object with a composition of rock and ices, likely including water, methane, and nitrogen. It is expected to have a surface layer composed mostly of frozen volatiles, such as methane and water ice, with a possible rocky core. The exact structure of Sedna's interior and exterior layers is still uncertain due to limited observational data.
