Here we describe the novel, multi-point Comet Interceptor mission. It is dedicated to the
exploration of a little-processed long-period comet, possibly entering the inner Solar System …

A comet is a highly dynamic object, undergoing a permanent state of change. These
changes have to be carefully classified and considered according to their intrinsic temporal …

We study the development of activity in the incoming long-period comet C/2017 K2 over the
heliocentric distance range 9≲ r H≲ 16 au. The comet continues to be characterized by a …

We report a statistically significant detection of nongravitational acceleration on the
subkilometer near-Earth asteroid (523599) 2003 RM. Due to its orbit, 2003 RM experiences …

The mechanism of dust emission from a cometary nucleus is still an open question and
thermophysical models have problems reproducing outgassing and dust productions rates …

Abstract Comet 67P/Churyumov‐Gerasimenko displays a pronounced hemispherical
dichotomy in surface morphology, where the southern hemisphere exhibits more erosional …

Context. The process of gas-driven ejection of refractory materials from cometary surfaces
continues to pose a challenging question in cometary science. The activity modeling of …

We measure the photometric color in the inner coma of Comet 29P/Schwassmann–
Wachmann 1 on nine nights in August and October, 2018. We see variations in the color …

Context. One of the primary goals of the European Space Agency's Rosetta mission to comet
67P/Churyumov-Gerasimenko was to investigate the mechanisms responsible for cometary …

Context. An assessment of the dust environment of a comet is needed for data analysis and
planning spacecraft missions, such as ESA's Comet Interceptor (CI) mission. The distinctive …
