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.

What gases make up Sedna's atmosphere?

It is believed that Sedna, a distant dwarf planet in our solar system, does not have a significant atmosphere due to its extreme distance from the sun. Therefore, it is unlikely to have any gases that make up an atmosphere similar to that of planets closer to the sun.


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?

How many minutes does it take light to travel from the sun to sedna?

The distance from the Sun to Sedna is approximately 86 astronomical units (AU). Since light travels at a speed of about 186,282 miles per second, it would take roughly 13.7 hours for light to travel from the Sun to Sedna. This is equivalent to around 822 minutes.

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.
