Abstract

On 12 November 2014, during the descent of the Rosetta lander Philae to the surface of comet 67P/Churyumov–Gerasimenko the Dust Impact Monitor (DIM) on board Philae recorded an impact of a cometary dust impact of a cometary dust particle at 2.4 km from the comet surface (5 km from the nucleus’ barycentre). In this work, we report further experiments that support the identification of this particle. We use aerogel as a comet analog material to characterise the properties of this particle. Our experiments show that this particle has a radius of 0.9 mm, a low density of 0.25 g/cm³ and a high porosity close to 90%. The particle likely moved at near 4 m/s with respect to the comet.
