Force on Planet Moving in Interstellar Dust - Physics Forums
Dec 3, 2010. Dust Force Interstellar Planet. In summary, the problem involves a spherical planet moving at a uniform speed through a cloud of interstellar dust particles. The dust particles are attracted to the planet and some would eventually fall onto its surface. The task is to find the retarding force on the planet due to the dust cloud.
Interstellar Dust: Extinction & Photon Ratio - Physics Forums
2007年10月23日 · Interstellar dust refers to the small particles, typically less than 1 micrometer in size, that exist in the space between stars. These particles can absorb, scatter, and reflect light, leading to a phenomenon known as extinction, where the intensity of light decreases as it travels through the dust.
