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.

What is the outermost portion of the solar atmosphere called?
The outermost portion of the solar atmosphere is called the corona. It is a region of very hot and tenuous plasma that can be seen during a total solar eclipse as a white halo surrounding the Sun.
Does Gravity pull on gases and if so why and how?
Yes, gravity pulls on gases just like it pulls on solid and liquid matter. This is because gravity is a fundamental force that acts on all objects with mass, including gas molecules. Gas molecules are attracted towards the center of mass of a celestial body due to the force of gravity, which is why they are found in the atmosphere surrounding planets.
How far is it from the earth to reach outside of the earth's atmosphere?
The boundary between Earth's atmosphere and outer space is known as the Kármán line, which is approximately 62 miles (100 kilometers) above sea level. Beyond this point is considered outer space, so reaching outside of Earth's atmosphere would require traveling a minimum of 62 miles above the Earth's surface.
What is a heliosphere?
a heliosphere is a bubble around the solar system blown by the the solar wind.
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 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.
Words that start with the prefix helio?
Heliotrope, heliocentric, heliosphere...
Boundary point in space where the solar system ends?
The heliosphere boundary.
What do astronomers think forms the heliosphere?
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.
Which company performs Heliosphere act with acrobatics and helium gas balloons?
see related link for information.
What is the name of the giant bubble of charged gas that surrounds the sun?
The giant bubble of charged gas that surrounds the sun is called the heliosphere. It is created by the solar wind, a stream of charged particles emanating from the sun. The heliosphere extends far beyond the furthest planets in our solar system.
What is a termination shock region?
The termination shock region is the outer boundary of the heliosphere, where the solar wind slows down as it encounters the pressure from the interstellar medium. This region is where the solar wind transitions from supersonic to subsonic speeds. It marks the beginning of the heliosheath, the outer region of the heliosphere.
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.
Does the heliopause mark the end of the suns gravitational grasp?
No, the heliopause is the boundary where the solar wind from the Sun meets the interstellar medium. Beyond the heliopause is where the Sun's influence diminishes, but its gravitational pull extends far beyond this boundary.
What is the name of the astrological area that the gravitational force of the sun stop?
Depends - it is uncertain where the boundary is, but one possible answer is the termination shock (heliosphere) after that the heliopause. [See related link]
