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.
22 lut 2021 · For Phobos, \({{\Delta }}{e}_{2:1}^{{\rm{Mars}}}=0.032\), \({{\Delta }}{e}_{3:1}^{{\rm{Mars}}}=0.002\) and \({{\Delta }}{e}_{1:1}^{{\rm{Sun}}}=0.0085\), whereas for Deimos, \({{\Delta...
18 kwi 2018 · The lower end of the basin-forming impactor size/energy estimates is consistent with Phobos-Deimos originating from the Borealis event, with subsequent Utopia and Hellas impacts producing less massive and more compact disks that did not yield long-lived moons.
15 maj 2015 · Although the two moons of Mars, Phobos and Deimos, have long been thought to be captured asteroids, recent observations of their compositions and orbits suggest that they may have formed from debris generated by one or more giant impacts of bodies with ∼0.01× target mass.
8 gru 2017 · Phobos and Deimos bear more resemblance to asteroids than to Earth's moon. Both are tiny — the larger, Phobos, is only 14 miles across (22 kilometers), while the smaller, Deimos, is only...
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.
