117: 2646: 45: 266: 3071: 208:. Within this region is the Local Interstellar Cloud (LIC), an area of slightly higher hydrogen density. It is estimated that the Solar System entered the LIC within the past 10,000 years. It is uncertain whether the Sun is still inside of the LIC or has already entered a transition zone between the LIC and the G cloud. A recent analysis estimates the Sun will completely exit the LIC in no more than 1,900 years. 3008: 2996: 3047: 3059: 2622: 1011: 2634: 3035: 1063: 290:(pT), against previous estimates of 180 to 250 pT). The fact that the Local Interstellar Cloud is strongly magnetized could explain its continued existence despite the pressures exerted upon it by the winds that blew out the Local Bubble. 465:
