Sedna is about 90 Astronomical Units from the Sun, at present. That's about 3 times further than Pluto. It's near to its closest approach to the Sun.
It can get to about 75 AU at its nearest, but reaches over 900 AU from the Sun at its most distant. Its average distance is about 520 AU.

It has a very "eccentric" orbit and can get to about 75 AU from the Sun at its
closest, but is over 900 AU at its greatest distance.

∙ 13y agoSedna's distance from the sun varies by a huge amount due to its eccentric orbit. At its closest it is 76.4 AU, while at its furthest is it 960.8 AU (one AU is the Earth to Sun distance of 150,000,000 km). Currently it is nearly at its closest distance of around 90 AU. It takes over 10,000 years to make one orbit of the sun.

It's currently about 90 AU from the sun (90 times as far away from the Sun as the Earth is), but it's in the part of its orbit where it's near its closest approach to the Sun; it spends most of it's "year" much further away (at its furthest, it's estimated to get nearly 1000 AU from the Sun).

How many moons does sedna have?
Sedna has no moons.
What gases make up Sedna's atmosphere?
It appears that there is no atmosphere on Sedna.
How far is the earths moon from mercury?
Varying from the the distance from the Earth to the Moon + the distance from the sun to the earth + the distance from mercury to the sun, to the distance from the earth to the sun - the distance from mercury to the sun - the distance from the earth to the moon

Can you live on sedna?
no
How many km is sedna from sun?
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.
Which is further sedna or heliosphere?
The heliosphere starts right here (or, you might say, at the Sun). Sedna is much further out. However, the heliosphere extends far out beyond Pluto. So the outer boundary of the heliosphere can be beyond Sedna. Sedna has an orbit that is very "eccentric" (highly elliptical). It's distance from the Sun varies greatly as it orbits. So, whether Sedna is inside or outside of the heliosphere changes with time.
Does Sedna also orbit around other dwarf planets?
No. Sedna orbits the sun.
Is sedna a tenth planet from the sun?
no
Where is Sedna located in the Solar System?
sedna is located in the Oort cloud and is the farthest object from the sun that we have discovered yet.
What is sedna and how can be the scientist prove that sedna is a new planet or just the moon of Pluto?
Sedna is a dwarf planet. It is to far away to be one of plutos moons and is proved to orbit the sun
Is there an atmosphere on Sedna?
Due its distance, it is not known for sure if Sedna does have an atmosphere. Scientists have speculated that a tenuous atmosphere may exist for some of its orbit, from the Nitrogen that is present.
Which planet moves around the sun at the slowest speed of any planet?
Sedna.
Does Sedna the planet orbit another star?
Sedna, like all objects in our Solar System orbit the Sun. The Sun and thus everything else, also orbit around the central core of our Galaxy - The Milky Way.
Which planet is the furthhest from the sun?
The furthest planet in our solar system from the sun is Sedna. It would take about 10,500 to 12,000 year to get there!
What is a sedna?
Not "a" Sedna; just "Sedna". Sedna is the Inuit goddess of the sea. Also, a dwarf planet named after this goddess.
