The G-Cloud (or G-Cloud complex) is an interstellar cloud located next to the Local Interstellar Cloud. The Sun is currently moving towards it. It is currently unknown whether the Sun is embedded in the Local Interstellar Cloud, or in the region where the two clouds are interacting. The G-Cloud contains the stars Alpha Centauri, Proxima Centauri and Altair (and possibly others).[2][3][4][5][6][7]
