This chapter reviews the estimates of the dust-to-gas and refractory-to-ice mass ratios
derived from Rosetta measurements in the lost materials and the nucleus of 67P/Churyumov …

The international Rosetta mission was launched in 2004 and consists of the orbiter
spacecraft Rosetta and the lander Philae. The aim of the mission is to map the comet …

The processes that led to the formation of the planetary bodies in the Solar system are still
not fully understood. Using the results obtained with the comprehensive suite of instruments …

Context. We investigate the formation and evolution of comet nuclei and other trans-
Neptunian objects (TNOs) in the solar nebula and primordial disk prior to the giant planet …

The physical properties of cometary nuclei observed today relate to their complex history
and help to constrain their formation and evolution. In this article, we review some of the …

The Philae lander accomplished the first soft landing and the first scientific experiments of a
human-made spacecraft on the surface of a comet. Planned, expected and unexpected …

Context. The origin of the particular shape of comet 67P/Churyumov-Gerasimenko (67P) is a
topic of active research. How and when it acquired its peculiar characteristics has distinct …

Our knowledge of the internal structure of asteroids is, so far, indirect–relying entirely on
inferences from remote sensing observations of the surface, and theoretical modeling of …

ABSTRACT Between 2014 December 31 and 2015 March 17, the OSIRIS cameras on
Rosetta documented the growth of a wide and deep depression in the Hapi region on Comet …

One of the key goals of the Rosetta mission was to understand how, where and when
comets formed in our solar system. There are two major hypotheses for the origin of comets …
