太阳系周围的星际云调节着太阳的银河系环境，并制约着行星际介质的物理特性。本文将太阳系内观测到的星际尘埃颗粒特性与从太阳系周围云的观测中推断出的尘埃特性进行了比较。在太阳附近的漫射云的属性进行了讨论，以了解过去的太阳漫射云复杂的流动的属性。在未来104-106年内，太阳的银河系环境将发生变化。太阳星际环境的变化和太阳活动周期的综合历史将记录在沉积在地质惰性表面上的大中型星际尘埃颗粒的比例变化中。结合来自太阳系内外的月球核心样本的数据将有助于解开这两种影响。
The interstellar cloud surrounding the solar system regulates the galactic environment of the Sun and constrains the physical characteristics of the interplanetary medium. This paper compares interstellar dust grain properties observed within the solar system with dust properties inferred from observations of the cloud surrounding the solar system. Properties of diffuse clouds in the solar vicinity are discussed to gain insight into the properties of the diffuse cloud complex flowing past the Sun. Evidence is presented for changes in the galactic environment of the Sun within the next 104–106 years. The combined history of changes in the interstellar environment of the Sun, and solar activity cycles, will be recorded in the variability of the ratio of large- to medium-sized interstellar dust grains deposited onto geologically inert surfaces. Combining data from lunar core samples in the inner and outer solar system will assist in disentangling these two effects.
