Almahata Sitta (=asteroid 2008 TC3) and the search for the ureilite parent body
This article explores what the recovery of 2008 TC3 in the form of the Almahata Sitta meteorites may tell us about the source region of ureilites in the main asteroid belt. An investigation is made into what is known about asteroids with roughly the same spectroscopic signature as 2008 TC3. A population of low-inclination near-Earth asteroids is identified with spectra similar to 2008 TC3. Five...
متن کاملMagnetism and mineralogy of Almahata Sitta polymict ureilite (= asteroid 2008 TC3): Implications for the ureilite parent body magnetic field
The Almahata Sitta meteorite is the first case of recovered extraterrestrial material originating from an asteroid that was detected in near Earth space shortly before entering and exploding in the high atmosphere. The aims of our project within the 2008 TC3 consortium were investigating Almahata Sitta’s (AS) magnetic signature, phase composition and mineralogy, focussing on the opaque minerals...

متن کاملSurface thermophysical properties determination of OSIRIS-REx target asteroid (101955) Bennu
In this work, we investigate the thermophysical properties of OSIRIS-REx target asteroid (101955) Bennu (hereafter Bennu), where thermal inertia plays an important role in understanding the nature of the asteroid’s surface, and will definitely provide substantial information for the sampling return mission. Using a thermophysical model incorporating, the recently updated 3D radar-derived shape ...
متن کاملComparing the Neatm with a Rotating, Cratered Thermophysical Asteroid Model
A cratered asteroid acts somewhat like a retroflector, sending light and infrared radiation back toward the Sun, while thermal inertia in a rotating asteroid causes the infrared radiation to peak over the “afternoon” part. In this paper a rotating, cratered asteroid model is described, and used to generate infrared fluxes which are then interpreted using the Near Earth Asteroid Thermal Model (N...
