Fast and Slow Rotation of Asteroids

  title={Fast and Slow Rotation of Asteroids},
  author={Petr Pravec and Alan W. Harris},
Abstract We present an analysis of the distribution of asteroid spin rates vs. size. The existence of significant populations of both slow and fast rotators among asteroids smaller than D=40 km, and especially below 10 km (where our sample is mostly near-Earth asteroids), is shown. We have found that the excess of slow rotators is present at spin rates below ≈0.8 rev/day, and the group of fast rotators occupies the range of spin rates >7 rev/day. The fast rotators show interesting… Expand

Spin rate distribution of small asteroids
Abstract The spin rate distribution of main belt/Mars crossing (MB/MC) asteroids with diameters 3–15 km is uniform in the range from f = 1 to 9.5 d−1, and there is an excess of slow rotators with f 1Expand
On the Slow Rotation of Asteroids
Abstract Asteroids with very slow rotation rates, up to 100 times slower than the mean for ordinary asteroids, are clearly a statistically distinct population from the rest. The cause of such slowExpand
Sphericity Preference in Shapes of Sub-km-Sized Fast-Rotating Main-Belt Asteroids
Here, we report on results of statistical analyses on spin periods and shapes of main-belt asteroids (MBAs) smaller than � 1 km in diameter, which were derived from lightcurve observations of aExpand
Spins of large asteroids: Hint on a primordial distribution of their spin rates
The Asteroid Belt and the Kuiper Belt are relics from the formation of our solar system. Understanding the size and spin distribution of the two belts is crucial for a deeper understanding of theExpand
Spin distribution of asteroids - Statistical model revisited
Abstract The distribution of the rotational frequencies of asteroids is believed to carry important information on their formation and the subsequent evolutionary processes (Burns, 1975). InExpand
Dynamical Evolution of Asteroids and Meteoroids Using the Yarkovsky Effect
The Yarkovsky effect is a thermal radiation force which causes objects to undergo semimajor axis drift and spin up/down as a function of their spin, orbit, and material properties. This mechanism canExpand
Statistical evidence for fast and slow asteroid rotations using Bayesian methods
Asteroid rotation rates have been analysed by many authors in the past. The statistical results and physical interpretations of the models have varied widely. Bayesian statistics are used here toExpand
Lightcurve Analysis of Four New Monolithic Fast-Rotating Asteroids
Abstract We present lightcurves and analysis for four new monolithic fast-rotating asteroids: 2000 AG 6 , 2000 DO 8 , 2000 EB 14 , and 2000 HB 24 . Their rotation periods of 4.60, 1.30, 107.47, andExpand
Photometric survey of the very small near-Earth asteroids with the SALT telescope , III. Lightcurves and periods for 12 objects and negative detections
Aims. Very small asteroids (VSAs) are thought to be the building blocks of larger asteroids and, as such, are interesting to study. Many of these monolithic or deeply fractured objects display rapidExpand
The Effect of Yarkovsky Thermal Forces on the Dynamical Evolution of Asteroids and Meteoroids
The Yarkovsky effect is a thermal radiation force that causes objects to undergo semimajor axis drift and spinup/spindown as a function of their spin, orbit, and material properties. This mechanismExpand


Asteroid rotation rates - Distributions and statistics
An analysis of asteroid rotation rates and light-curve amplitudes disclosed many significant correlations between these rotation parameters and asteroid diameter, with distinct changes occurring nearExpand
Asteroid rotation rates: II. A theory for the collisional evolution of rotation rates
Abstract A model for the evolution of the mean rotation rate of asteroids arising from mutual collisions yields reasonable agreement with observed rotation rates. The mean rotation rate of largeExpand

Radiative Spin-up and Spin-down of Small Asteroids
The Yarkovsky–O'Keefe–Radzievskii–Paddack (YORP) effect may spin up or spin down 5-km-radius asteroids on a 108-year timescale. Smaller asteroids spin up or down even faster due to the radius-squaredExpand

Asteroid collisional history - Effects on sizes and spins
The effects of asteroid collisional history on sizes and spins of present-day objects are discussed. Collisional evolution studies indicate that collisions have altered the spin-rates of smallExpand

Abstract Photoelectric observations of 32 asteroids observed from Table Mountain Observatory during the second half of 1978 are reported. Rotation periods were obtained for most objects. AbsoluteExpand
How fast can an asteroid spin
Abstract Many large asteroids are probably gravitationally bound “rubble piles,” which should approximate figures of hydrostatic equilibrium. The maximum angular velocity of such bodies is limited byExpand
