Size Constraints for the Pre-atmospheric Parent Bodies of Ordinary Chondrites

Juan A. Sanchez, David C. Cantillo, Adam Battle +7

The study of S-complex near-Earth objects (NEOs), the parent bodies of ordinary chondrites, has shown that they are dominated by asteroids with LL chondrite-like compositions. This…

Analysis of Karin and Koronis2 asteroid families: new findings and challenges

David Vokrouhlický, David Nesvorný, William F. Bottke

We use our home catalog of the asteroid proper elements to study the Karin family. The hierarchical clustering method provides formal identification with 3,863 members, but this se…

Size-Frequency Distribution of Terrestrial Leftover Planetesimals and S-complex Implanted Asteroids

Rogerio Deienno, Andre Izidoro, David Nesvorny +3

The isotopic composition of meteorites linked to S-complex asteroids has been used to suggest that these asteroids originated in the terrestrial planet's region, i.e., within 1.5 a…

Origin of Asteroid (101955) Bennu and its Connection to the New Polana Family

Driss Takir, Joshua P. Emery, William F. Bottke +1

The asteroid (142) Polana is classified as a B-type asteroid located in the inner Main Belt. This asteroid is the parent of the New Polana family, which has been proposed to be the…

A Contact Binary Satellite of the Asteroid (152830) Dinkinesh

Harold F. Levison, Simone Marchi, Keith S. Noll +3

Asteroids with diameters less than about 5 km have complex histories because they are small enough for radiative torques, YORP, to be a notable factor in their evolution. (152830)…

NEOMOD 3: The Debiased Size Distribution of Near Earth Objects

David Nesvorny, David Vokrouhlicky, Frank Shelly +9

Our previous model (NEOMOD2) for the orbital and absolute magnitude distribution of Near Earth Objects (NEOs) was calibrated on the Catalina Sky Survey observations between 2013 an…

The population of small near-Earth objects: composition, source regions and rotational properties

Juan A. Sanchez, Vishnu Reddy, Audrey Thirouin +7

The study of small (300 m) near-Earth objects (NEOs) is important because they are more closely related than larger objects to the precursors of meteorites that fall on Earth. C…

Accretion and Uneven Depletion of the Main Asteroid Belt

Rogerio Deienno, David Nesvorny, Matthew S. Clement +3

The main asteroid belt (MAB) is known to be primarily composed of objects from two distinct taxonomic classes, generically defined here as S- and C-complex. The former probably ori…

Orbital and absolute magnitude distribution of Jupiter Trojans

David Vokrouhlický, David Nesvorný, Miroslav Brož +4

Jupiter Trojans (JTs) librate about the Lagrangian stationary centers L4 and L5 associated with this planet on a typically small-eccentricity and moderate-inclination heliocentric…

NEOMOD 2: An Updated Model of Near-Earth Objects from a Decade of Catalina Sky Survey Observations

David Nesvorny, David Vokrouhlicky, Frank Shelly +9

Catalina Sky Survey (CSS) is a major survey of Near-Earth Objects (NEOs). In a recent work, we used CSS observations from 2005-2012 to develop a new population model of NEOs (NEOMO…

Origin and Evolution of Jupiter's Trojan Asteroids

William F. Bottke, Raphael Marschall, David Nesvorný +1

The origin of the Jupiter Trojan asteroids has long been a mystery. Dynamically, the population, which is considerably smaller than the main asteroid belt, librates around Jupiter'…

A Crater Chronology for the Jupiter's Asteroids

S. Marchi, D. Nesvorný, D. Vokrouhlický +2

We present a new crater chronology for Jupiter's Trojan asteroids. This tool can be used to interpret the collisional history of the bodies observed by NASA's Lucy mission. The Luc…

The NEO Surveyor Near Earth Asteroid Known Object Model

Tommy Grav, Amy K. Mainzer, Joseph R. Masiero +4

The known near-Earth object (NEO) population consists of over 32,000 objects, with a yearly discovery rate of over 3000 NEOs per year. An essential component of the next generation…
