Question

Is the Solar Wind comprised of actual matter along with energy?  If so, is there a point at which the gravitational attraction of the Sun overcomes the Solar Wind?

Michael Adkins · Accepted Answer

The solar wind does have matter as well as energy. But instead of being reined in by the Sun's gravity, it eventually merges into the interstellar medium.

The heliosphere is the area in space where the solar wind predominates the flow of matter, and the heliopause is the outer boundary of the heliosphere where the merger with the stellar wind occurs.

undefined Yes, the solar wind is made up of energy and charged particles, mostly protons and electrons, and it comes from the Sun's corona, which is its outermost atmosphere. The Sun's gravitational pull prevents the solar wind from moving too far away from it, which keeps most of the particles inside its gravitational field, though some particles are able to escape and form the solar wind.
