NATIONAL HARBOR, Md. — A small comet broke a rotation-speed record in a big way: New work reveals that an icy rock known as 41P dramatically slowed its spin at an unprecedented rate in 2017 ...

Figure 3: Rotation periods for comet 41P measured as a function of time relative to perihelion. We extrapolated the rotation period of the comet in time to investigate its possible past and future ...

On page 186, Bodewits et al. 2 report a dramatic decrease in the rotation rate of comet 41P/Tuttle–Giacobini–Kresák (comet 41P) indicating that this object could soon enter a phase of ...

One team of scientists, from the University of Maryland, watched the comet’s rotation rate drop rapidly, from one rotation every 20 hours to one every 46 hours. This is larger than any change in ...

Planetary Science Institute researchers have discovered a way to predict the changes in the rotational states of comets that could help scientists learn more about the approaching Comet C/2012 S1 ...

Planetary Science Institute (PSI) researchers have discovered a way to predict the changes in the rotational states of comets that could help scientists learn more about the approaching Comet ISON ...

Describing the event as the “lingering death” of the object, the team says that its study reveals some highly unusual features in the comet’s colour and rotation. The innermost reaches of the solar ...
