👉 Mesopause is a term used in astrophysics and astronomy to describe the transition from the solar neighborhood, which is the region of the sun where the Earth orbits around the Sun, to the interstellar medium, or beyond the heliocentric orbit. During this transition, the temperature drops drastically, causing the outer layers of the solar system to lose their heat and become extremely cold, known as a "hot spot." This phenomenon occurs when the Sun's magnetic field becomes stronger than the gravitational pull on
