The Debiased Near-Earth Object Population from ATLAS Telescopes
Rogerio Deienno, Larry Denneau, David Nesvorný +7
This work is dedicated to debias the Near-Earth Objects (NEO) population based on observations from the Asteroid Terrestrial-impact Last Alert System (ATLAS) telescopes. We have ap…
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…
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…
NEOMOD: A New Orbital Distribution Model for Near Earth Objects
David Nesvorny, Rogerio Deienno, William F. Bottke +10
Near Earth Objects (NEOs) are a transient population of small bodies with orbits near or in the terrestrial planet region. They represent a mid-stage in the dynamical cycle of aste…
The impact and recovery of asteroid 2018 LA
Peter Jenniskens, Mohutsiwa Gabadirwe, Qing-Zhu Yin +63
The June 2, 2018, impact of asteroid 2018 LA over Botswana is only the second asteroid detected in space prior to impacting over land. Here, we report on the successful recovery of…
Spitzer Observations of Interstellar Object 1I/`Oumuamua
DE Trilling, M Mommert, JL Hora +20
1I/`Oumuamua is the first confirmed interstellar body in our Solar System. Here we report on observations of `Oumuamua made with the Spitzer Space Telescope on 2017 November 21--22…
Search for OH 18-cm radio emission from 1I/2017 U1 with the Green Bank telescope
Ryan S. Park, D. J. Pisano, T. Joseph W. Lazio +2
This paper reports the first OH 18-cm line observation of the first detected interstellar object 1I/2017 U1 (`Oumuamua) using the Green Bank Telescope. We have observed the OH line…
The atmospheric impact trajectory of asteroid 2014 AA
D. Farnocchia, S. R. Chesley, P. G. Brown +1
Near-Earth asteroid 2014 AA entered the Earth's atmosphere on 2014 January 2, only 21 hours after being discovered by the Catalina Sky Survey. In this paper we compute the trajecto…
Physical Properties of Near-Earth Asteroid 2011 MD
M. Mommert, D. Farnocchia, J. L. Hora +7
We report on observations of near-Earth asteroid 2011 MD with the Spitzer Space Telescope. We have spent 19.9 h of observing time with channel 2 (4.5 μm) of the Infrared Array Came…
Trajectory analysis for the nucleus and dust of comet C/2013~A1 (Siding Spring)
Davide Farnocchia, Steven R. Chesley, Paul W. Chodas +3
Comet C/2013 A1 (siding Spring) will experience a high velocity encounter with Mars on October 19, 2014 at a distance of 135,000 km +- 5000 km from the planet center. We present a…
Orbit and Bulk Density of the OSIRIS-REx Target Asteroid (101955) Bennu
Steven R. Chesley, Davide Farnocchia, Michael C. Nolan +13
The target asteroid of the OSIRIS-REx asteroid sample return mission, (101955) Bennu (formerly 1999 RQ), is a half-kilometer near-Earth asteroid with an extraordinarily well…
Yarkovsky-driven impact risk analysis for asteroid (99942) Apophis
D. Farnocchia, S. R. Chesley, P. W. Chodas +5
We assess the risk of an Earth impact for asteroid (99942) Apophis by means of a statistical analysis accounting for the uncertainty of both the orbital solution and the Yarkovsky…
Comet C/2011 W3 (Lovejoy): Orbit Determination, Outbursts, Disintegration of Nucleus, Dust-Tail Morphology, and Relationship to New Cluster of Bright Sungrazers
Zdenek Sekanina, Paul W. Chodas
We describe the physical and orbital properties of C/2011 W3. After surviving perihelion, the comet underwent major changes (permanent loss of nuclear condensation, formation of sp…
The impact of a large object with Jupiter in July 2009
A. Sánchez-Lavega, A. Wesley, G. Orton +13
On 2009 July 19, we observed a single, large impact on Jupiter at a planetocentric latitude of 55^{\circ}S. This and the Shoemaker-Levy 9 (SL9) impacts on Jupiter in 1994 are the o…
