The heliosphere blown by the solar wind, within which all the major planets of the Solar System are embedded, is a small example of a stellar-wind bubble. Stellar-wind bubbles have a two-shock structure. [1] The freely-expanding stellar wind hits an inner termination shock, where its kinetic energy is thermalized, producing 10 6 K, X-ray ...
Just as some interstellar pressure was detected as early as 2004, some of the Sun's material seeps into the interstellar medium. [47] The heliosphere is thought to reside in the Local Interstellar Cloud inside the Local Bubble, which is a region in the Orion Arm of the Milky Way Galaxy.
These high-energy stellar winds blow stellar wind bubbles. In planetary nebula NGC 6565, a cloud of gas was ejected from the star after strong stellar winds. [8] G-type stars like the Sun have a wind driven by their hot, magnetized corona. The Sun's wind is called the solar wind.
An interstellar cloud is generally an accumulation of gas, plasma, and dust in our and other galaxies. But differently, an interstellar cloud is a denser-than-average region of the interstellar medium , the matter and radiation that exists in the space between the star systems in a galaxy.
This is the boundary of the Solar System to interstellar space. The outermost region of the Solar System is the theorized Oort cloud, the source for long-period comets, extending to a radius of 2,000–200,000 AU. The closest star to the Solar System, Proxima Centauri, is 4.25 light-years (269,000 AU) away.

The Local Bubble, or Local Cavity, [3] is a relative cavity in the interstellar medium (ISM) of the Orion Arm in the Milky Way.It contains the closest of celestial neighbours and among others, the Local Interstellar Cloud (which contains the Solar System), the neighbouring G-Cloud, the Ursa Major moving group (the closest stellar moving group) and the Hyades (the nearest open cluster).
