29 lis 2021 · Imaging data reveals a low albedo of both moons – Phobos: ∼0.07; Deimos: ∼0.08. Also, Phobos manifests distinct redder and bluer units, whereas the surface of Deimos is globally comparable to the Phobos redder units with localized streaks of brighter material.
18 sie 2017 · Phobos and Deimos are the two small moons of Mars. Recent works have shown that they can accrete within an impact-generated disk. However, the detailed structure and initial thermodynamic properties of the disk are poorly understood.
10 sie 2022 · Phobos values were measured in the range between 40 and 70 J K −1 m −2 s 1/2, while Deimos values were in the range between 25 and 84 J K −1 m −2 s 1/2. This suggest that both moons are covered by a uniform layer of several cm of finely divided material ( 50 − 100 μ m particle size).
1 lut 2011 · An alternative hypothesis that is frequently overlooked is the possibility that Phobos and Deimos are the result of a giant impact. Such an idea was first suggested by Singer (1966), who proposed that Phobos and Deimos may have been “kicked” off the martian surface by a meteorite impact.
Rare, D-Type Spectrum. Deimos has a D-type spectrum, and most of Phobos as well, i.e., they are both very dark and very red. That these two inner solar system small bodies have D-type spectra is remark-able, because most D-type asteroids are found in the outer main belt and beyond, and among Jupiter Tro-jans. D-Types are rare among NEAs.

ABSTRACT. Recent works have shown that Martian moons Phobos and Deimos may have accreted within a giant impact-generated disk whose composition is about an equal mixture of Martian material and impactor material.
