The shape and spin state of (275677) 2000 RS11 from ground-based radar and optical observations
Richard E. Cannon, Agata Rożek, Kaley Brauer +12
Near-Earth asteroid (275677) 2000 RS11 was observed over 5 days in March 2014 with both the Arecibo (2380 MHz, 12.6 cm) and Goldstone (8560 MHz, 3.5 cm) planetary radar systems. Th…
Orbital Period Change of Dimorphos Due to the DART Kinetic Impact
Cristina A. Thomas, Shantanu P. Naidu, Peter Scheirich +46
The Double Asteroid Redirection Test (DART) spacecraft successfully performed the first test of a kinetic impactor for asteroid deflection by impacting Dimorphos, the secondary of…
Citizen Science Astronomy with a Network of Small Telescope: The Launch and Deployment of JWST
R. A. Lambert, F. Marchis, F. +54
We present a coordinated campaign of observations to monitor the brightness of the James Webb Space Telescope (JWST) as it travels toward the second Earth-Sun Lagrange point and un…
Spin state and moment of inertia of Venus
Jean-Luc Margot, Donald B. Campbell, Jon D. Giorgini +4
Fundamental properties of the planet Venus, such as its internal mass distribution and variations in length of day, have remained unknown. We used Earth-based observations of radar…
Bistatic Radar Observations of Near-Earth Asteroid (163899) 2003 SD220 from the Southern Hemisphere
Shinji Horiuchi, Blake Molyneux, Jamie B. Stevens +13
We report results of Canberra-ATCA Doppler-only continuous wave (CW) radar observations of near-Earth asteroid (163899) 2003 SD220 at a receiving frequency of 7159 MHz (4.19 cm) on…
Linking the Solar System and Extrasolar Planetary Systems with Radar Astronomy: Infrastructure for "Ground Truth" Comparison
Joseph Lazio, Amber Bonsall, Marina Brozovic +13
Planetary radars have obtained unique science measurements about solar system bodies and they have provided orbit determinations allowing spacecraft to be navigated throughout the…
Arecibo Radar Observations of Near-Earth Asteroid (3200) Phaethon During the 2017 Apparition
Patrick A. Taylor, Edgard G. Rivera-Valentin, Lance A. M. Benner +8
We report Arecibo S-band (2380 MHz; 12.6 cm) radar observations of near-Earth asteroid (3200) Phaethon during the December 2017 apparition when Phaethon passed within 0.07 au of Ea…
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…
Radar Imaging and Characterization of Binary Near-Earth Asteroid (185851) 2000 DP107
Shantanu P. Naidu, Jean-Luc Margot, Patrick A. Taylor +7
Potentially hazardous asteroid (185851) 2000 DP107 was the first binary near-Earth asteroid to be imaged. Radar observations in 2000 provided images at 75 m resolution that reveale…
Radar Imaging and Physical Characterization of Near-Earth Asteroid (162421) 2000 ET70
Shantanu P. Naidu, Jean-Luc Margot, Michael W. Busch +6
We observed near-Earth asteroid (162421) 2000 ET70 using the Arecibo and Goldstone radar systems over a period of 12 days during its close approach to the Earth in February 2012. W…
Characterizing Subpopulations within the Near Earth Objects with NEOWISE: Preliminary Results
A. Mainzer, T. Grav, J. Masiero +10
We present the preliminary results of an analysis of the sub-populations within the near-Earth asteroids, including the Atens, Apollos, Amors, and those that are considered potenti…
Time in the 10,000-Year Clock
Danny Hillis, Rob Seaman, Steve Allen +1
The Long Now Foundation is building a mechanical clock that is designed to keep time for the next 10,000 years. The clock maintains its long-term accuracy by synchronizing to the S…
Radar Observations and the Shape of Near-Earth Asteroid 2008 EV5
Michael W. Busch, Steven J. Ostro, Lance A. M. Benner +10
We observed the near-Earth asteroid 2008 EV5 with the Arecibo and Goldstone planetary radars and the Very Long Baseline Array during December 2008. EV5 rotates retrograde and its o…
