Interstellar interlopers are bodies formed outside of the Solar System but observed passing
through it. The first two identified interlopers, 1I/'Oumuamua and 2I/Borisov, exhibited …

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 bearing capacity-the ability of a surface to support applied loads-is an important
parameter for understanding and predicting the response of a surface. Previous work has …

INTRODUCTION On 1 January 2019, the New Horizons spacecraft passed 3538 km from
Kuiper Belt object (KBO)(486958) Arrokoth. Arrokoth is a contact binary consisting of two …

Dust particle sizes constrained from dust continuum and polarization observations by radio
interferometry are inconsistent by at least an order of magnitude. Motivated by porous dust …

ABSTRACT European Space Agency's Rosetta spacecraft at comet 67P/Churyumov–
Gerasimenko (67P) was the first mission that accompanied a comet over a substantial …

So-called 'dark comets' are small, morphologically inactive near-Earth objects (NEOs) that
exhibit nongravitational accelerations inconsistent with radiative effects. These objects …

Planetesimals—the initial stage of the planetary formation process—are considered to be
initially very porous aggregates of dusts,, and subsequent thermal and compaction …
