The spin state of asteroid Apophis and a prediction of its change during the 2029 close encounter with Earth
J. Durech, D. Vokrouhlicky, P. Pravec +23
On April 13, 2029, the asteroid Apophis will pass near Earth at a geocentric distance of about 38,000 km. Numerical models have suggested that the post-encounter spin state will cr…
NEO Colors from The Mission Accessible Near-Earth Object Survey (MANOS)
Nicholas Moskovitz, Theodore Kareta, Samantha Hemmelgarn +13
We present spectro-photometric griz colors for 189 near-Earth objects (NEOs) collected by the Mission Accessible Near-Earth Object Survey (MANOS). Data acquisition involved non-sim…
Comet C/2012 S1 (ISON) crossing the Jupiter orbit
Margarita Safonova, Noah Brosch, Shai Kaspi +4
We report results of intensive time-resolved imaging photometry and synoptic deep imaging of the comet C/2012 S1 (ISON) performed in February 2013. The data were obtained at the Wi…
Secular change in the spin states of asteroids due to radiation and gravitation torques. New detections and updates of the YORP effect
J. Ďurech, D. Vokrouhlický, P. Pravec +21
The rotation state of small asteroids is affected in the long term by perturbing torques of gravitational and radiative origin (the YORP effect). Direct observational evidence of t…
Near-IR Spectral Observations of the Didymos System -- Daily Evolution Before and After the DART Impact, Indicates Dimorphos Originated from Didymos
David Polishook, Francesca E. DeMeo, Brian J. Burt +4
Ejecta from Dimorphos following the DART mission impact, significantly increased the brightness of the Didymos-Dimorphos system, allowing us to examine sub-surface material. We rep…
Isolating the mechanisms for asteroid surface refreshing
F. E. DeMeo, M. Marsset, D. Polishook +10
Evidence is seen for young, fresh surfaces among Near-Earth and Main-Belt asteroids even though space-weathering timescales are shorter than the age of the surfaces. A number of me…
