The Solar System is located within a structure called the Local Bubble, a low-density region of the galactic interstellar medium.
[5] Within this region is the Local Interstellar Cloud (LIC), an area of slightly higher hydrogen density.
[3][6][7] A recent analysis estimates the Sun will completely exit the LIC in no more than 1,900 years.
However, its specific heat capacity is very low because it is not very dense, with 0.3 atoms per cubic centimetre (5/cu in).
[15] The Local Interstellar Cloud's potential effects on Earth are greatly diminished by the solar wind and the Sun's magnetic field.
