We review our current knowledge of comet 67P/Churyumov–Gerasimenko nucleus composition as inferred from measurements made by remote sensing and in-situ instruments aboard Rosetta orbiter and Philae lander. Spectrophotometric properties (albedos, color indexes and Hapke parameters) of 67P/CG derived by Rosetta are discussed in the context of other comets previously explored by space missions. Composed of an assemblage made of ices, organic materials and minerals, cometary nuclei exhibit very… 

Comet nuclei composition and evolution

Thanks to Rosetta orbiter’s and Philae lander’s data our knowledge of cometary nuclei composition has experienced a great advancement. The properties of 67P/Churyumov-Gerasimenko nucleus are

Chemical and Isotope Composition of Comet 67P/Churyumov−Gerasimenko: The Rosetta−Philae Mission Results Reviewed in the Context of Cosmogony and Cosmochemistry

The studies of the composition and structure of comet 67P/Churyumov–Gerasimenko—a short-period comet of Jupiter’s family—which was an object of the recent Rosetta–Philae space mission, yielded

Volatile Species in Comet 67P/Churyumov-Gerasimenko: Investigating the Link from the ISM to the Terrestrial Planets

Comets contain abundant amounts of organic and inorganic species. Many of the volatile molecules in comets have also been observed in the interstellar medium and some of them even with similar

Infrared detection of aliphatic organics on a cometary nucleus

The European Space Agency’s Rosetta mission 1 has acquired unprecedented measurements of the surface of the nucleus of comet 67P/Churyumov–Gerasimenko (hereafter, 67P), the composition of which, as

Cometary Nuclei—From Giotto to Rosetta

We will briefly recapitulate the beginning of modern cometary physic. Then we will assess the results of the cometary flyby missions previous to ESA’s Rosetta rendezvous with comet

Are there any pristine comets? Constraints from pebble structure

We show that if comets (or any small icy planetesimals such as Kuiper belt objects) are composed of pebble piles, their internal radiogenic as well as geochemical heating results in considerably

Hydroxylated Mg-rich Amorphous Silicates: A New Component of the 3.2 μm Absorption Band of Comet 67P/Churyumov–Gerasimenko

The VIRTIS imaging spectrometer on board Rosetta has shown that the nucleus surface of comet 67P/Churyumov–Gerasimenko (67P/CG) is characterized by a broad absorption band at around 3.2 μm. The

An orbital water-ice cycle on comet 67P from colour changes

Spectral analysis of the VIRTIS dataset shows two opposite seasonal colour cycles in the coma and on the surface of comet 67P/Churyumov–Gerasimenko, indicating an orbital water-ice cycle.

Organic Matter in Cometary Environments

Results both from Earth-based studies as well as spacecraft missions to comets are summarized, highlighted by the Rosetta mission, which orbited comet 67P/Churyumov–Gerasimenko for two years, providing unprecedented insights into the nature of comets.

Ammonium salts are a reservoir of nitrogen on a cometary nucleus and possibly on some asteroids

L Laboratory experiments show that comet 67P contains ammonium salts, which may dominate its nitrogen content, andSemivolatile compounds of low molecular weight, such as carboxylic (−COOH)–bearing molecules or ammonium (NH4+) ions, have been proposed as potential carriers of the 3.2-μm absorption feature.

Cometary nuclei contain the least modified material from the formative epoch of our planetary system, and their compositions reflect a range of processes experienced by material prior to its

Molecular nitrogen in comet 67P/Churyumov-Gerasimenko indicates a low formation temperature

Direct measurements of N2 by instruments aboard the Rosetta spacecraft provide clues about the comet’s long history and depletion of molecular nitrogen at levels that are depleted compared to those in the primordial solar system suggests that the comet formed at low-temperature conditions below ~30 kelvin.

The organic-rich surface of comet 67P/Churyumov-Gerasimenko as seen by VIRTIS/Rosetta

The VIRTIS instrument on board the Rosetta spacecraft has provided evidence of carbon-bearing compounds on the nucleus of the comet 67P/Churyumov-Gerasimenko, and no ice-rich patches are observed, indicating a generally dehydrated nature for the surface currently illuminated by the Sun.

Carbon-rich dust in comet 67P/Churyumov-Gerasimenko measured by COSIMA/Rosetta

Cometary ices are rich in CO2, CO and organic volatile compounds, but the carbon content of cometary dust was only measured for the Oort Cloud comet 1P/Halley, during its flyby in 1986. The COmetary

Compositional homogeneity in the fragmented comet 73P/Schwassmann–Wachmann 3

The chemical composition of two distinct fragments of 73P/Schwassmann–Wachmann 3 are remarkably similar in composition, in marked contrast to the chemical diversity within the overall comet population and contrary to the expectation that short-period comets should show strong compositional variation with depth in the nucleus owing to evolutionary processing from numerous close passages to the Sun.

Exposed water ice on the nucleus of comet 67P/Churyumov–Gerasimenko

The stratigraphy observed on comet 67P/Churyumov–Gerasimenko is the result of evolutionary processes affecting the uppermost metres of the nucleus and does not necessarily require a global layering to have occurred at the time of the comet’s formation.

Cosac, The Cometary Sampling and Composition Experiment on Philae

Comets are thought to preserve the most pristine material currently present in the solar system, as they are formed by agglomeration of dust particles in the solar nebula, far from the Sun, and their

Variations in cometary dust composition from Giotto to Rosetta, clues to their formation mechanisms

This paper reviews the current knowledge on the composition of cometary dust (ice, minerals and organics) in order to constrain their origin and formation mechanisms. Comets have been investigated by

Seasonal mass transfer on the nucleus of comet 67P/Chuyumov–Gerasimenko

We collect observational evidence that supports the scheme of mass transfer on the nucleus of comet 67P/Churyumov-Gerasimenko. The obliquity of the rotation axis of 67P causes strong seasonal

The presence of clathrates in comet 67P/Churyumov-Gerasimenko

Measurements of the time variation of major and minor volatile species in the coma of the Jupiter family comet 67P/Churyumov-Gerasimenko by the ROSINA (Rosetta Orbiter Spectrometer for Ion and Neutral Analysis) instrument onboard Rosetta provide insight into the possible origin of this comet.
