On 2029 April 13, near-Earth asteroid (NEA) (99942) Apophis will pass at a distance of ∼6 Earth radii from Earth. This event will provide researchers with a unique opportunity to study the effects of tidal forces experienced by an asteroid during a close encounter with a terrestrial planet. Binzel et al. predicted that close flybys of terrestrial planets by NEAs would cause resurfacing of their regolith due to seismic shaking. In this work, we present the best pre-encounter near-infrared… 

Physical Characterization of Active Asteroid (6478) Gault

Main belt asteroid (6478) Gault has been dynamically linked with two overlapping asteroid families: Phocaea, dominated by S-type asteroids, and Tamara, dominated by low-albedo C-types. This object

Photometric observations of the potentially hazardous asteroid (99942) Apophis from Kawabe Cosmic Park

Asteroid (99942) Apophis is a potentially hazardous asteroid. The Korea Astronomy and Space Science Institute (KASI) recently proposed a rendezvous mission with Apophis, with a planned asteroid


The 350-meter asteroid (99942) Apophis, an object 5-times larger and 100-times more massive than the Tunguska impactor, will safely miss the Earth on Friday April 13, 2029. However its close flyby

Terminus: A Versatile Simulator for Space-based Telescopes

Space-based telescopes offer unparalleled opportunities for characterizing exoplanets, solar system bodies, and stellar objects. However, observatories in low-Earth orbits (e.g., Hubble,

Search for the H Chondrite Parent Body among the Three Largest S-type Asteroids: (3) Juno, (7) Iris, and (25) Phocaea

Linking meteorites to source regions in the main asteroid belt is important for understanding the conditions under which their parent bodies formed. Ordinary chondrites are the most abundant class of



Thermal infrared observations of asteroid (99942) Apophis with Herschel

The near-Earth asteroid (99942) Apophis is a potentially hazardous asteroid. We obtained far-infrared observations of this asteroid with the Herschel Space Observatory PACS instrument at 70, 100, and

Spectral properties and composition of potentially hazardous Asteroid (99942) Apophis

Mineralogies and source regions of near-Earth asteroids

Observations, compositional, and physical characterization of near-Earth and Mars-crosser asteroids from a spectroscopic survey

Aims. We analyse a significantly large sample of spectroscopic data to provide a compositional characterization of the near-Earth asteroid population. We present visible and near-infrared spectra of

Mars Encounters cause fresh surfaces on some near-Earth asteroids

Pyroxene mineralogies of near‐Earth vestoids

Abstract— We have calculated pyroxene mineralogies of seven near‐Earth asteroids (NEAs) with reflectance spectra similar to HEDs (howardites, eucrites, and diogenites). Two different sets of formulas

Compositional differences between meteorites and near-Earth asteroids

It is reported that most near-Earth asteroids (including the potentially hazardous subset) have spectral properties quantitatively similar to the class of meteorites known as LL chondrites, and the prominent Flora family in the inner part of the asteroid belt shares the same spectral properties, suggesting that it is a dominant source of near- Earth asteroids.

Color and Albedo Heterogeneity of Vesta from Dawn

Dawn's observations confirm that Vesta is a small differentiated planetary body with an inner core, and represents a surviving proto-planet from the earliest epoch of solar system formation, and reveal its color and photometric diversity are indicative of its status as a preserved, differentiated protoplanet.
