Detection of Rotational Acceleration of Bennu using HST Lightcurve Observations

By Michael Nolan and others
We observed the near-Earth asteroid (101955) Bennu from the ground in 1999 and 2005, and with the Hubble Space Telescope in 2012, to constrain its rotation rate. The data reveal an acceleration of \(2.64 \pm 1.05 \times 10^{-6} \mathrm{deg\ day}^{-2}\), which could be due to a change in the moment... Show more
