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.

How many minutes does it take light to travel from the sun to sedna?
Sedna, a "dwarf planet" far beyond the orbit of Neptune, has a highly elliptical orbit with a perihelion of 76AU, or about 631 light-minutes from the Sun, and an aphelion of 975 AU, or about 8,093 light-minutes or 5.6 light-DAYS.
Who did the Inuits worship?
They worship anything involving nature. For example they worship Sedna: the goddess of the sea and they worship Anigan the god of the moon.

Not "a" Sedna; just "Sedna". Sedna is the Inuit goddess of the sea. Also, a dwarf planet named after this goddess.
What are the dimensions of the solar system?
The size of the Solar System depends partly on what are considered to be its outermost reaches. There are three main candidates:the aphelion of the orbit of the farthest planet,the farthest observable object which orbits the sun,or the edge of the heliosphere.The furthest distance from the sun reached by the outermost planet, Neptune, is approx 4.5 billion kilometres and this would give the Solar System a diameter of 9.1 billion km. (This definition depends on Eris remaining a dwarf planet and not attaining planetary status.)The most distance observable object in the Solar System is Sedna. It is 143.7 billion km from the Sun, thus giving the Solar System a diameter of 287.5 billion km or approx 1922 AU.The heliosphere is the region within which the solar wind pushes against the interstellar medium, or where the Sun's gravity is stronger than that of other stars. The edge of the heliosphere, called the heliopause is reached at a distance of 90 AU giving the heliosphere a diameter of 180 AU.Incidentally, although at its aphelion, Sedna is outside the heliosphere, its orbit is very eccentric and brings it to 76 AU at its nearest approach to the sun - well within the heliosphere.
How many moons does sedna have?
Sedna has no moons.
