The heliosphere is the area of space affected by the flow of charged particles being thrown off by the Sun. The solar corona, sometimes known as the Sun's "atmosphere", is the lowest and densest layer of the heliosphere, but the heliosphere and the "sloar wind" actually extends out beyond any of the planets. The Milky Way galaxy itself has an environment of charged particles; where this meets the heliosphere is the heliosheath or "termination shock" layer.
Only two space probes, the two Voyager probes, have reached the termination shock, which may be an irregularly shaped area somewhere between 75 AU from the Sun and 90 AU out. We have very little firm data about that area.

What is a heliosphere?
a heliosphere is a bubble around the solar system blown by the the solar wind.
Do astronomers think Pluto is a planet?
Astronomers think Pluto is a dwarf planet. And they're right.
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.
What is Heliosphere?
The heliosphere is a vast, bubble-like region of space surrounding the Sun, created by the solar wind. It is the region in which the Sun's influence, in the form of its magnetic field and charged particles, extends outward and interacts with the interstellar medium. The heliosphere plays a crucial role in protecting our solar system from cosmic radiation.
Do all astronomers think Pluto is a panet?
No. There are almost no astronomers that think Pluto is a planet. They know it's officially a dwarf planet.
What planet some astronomers don't think is a planet?
Astronomers have decided that Pluto does not meet the definition of a planet.
What is a bubble of space influenced by the sun called?
The bubble of space influenced by the sun is called the heliosphere. It is a region of space where the sun's influence dominates over the interstellar medium.
How long do astronomers estimate the sun will last before it begins to die?
Astronomers think the sun will die in 2012
What tool do you think helped astronomers study the sky is the most?
The telescope helps astronomers the most when studying the sky.
What did ancient astronomers think was the center of the universe?
it is earth
How do astronomers think they know about the distance of stars?
They dont
What is the planet that astronomers don't think is a planet?
