Worldwide Help Sought For Comet Study Effort
Planetary Science Institute | 2016 Nov 22
Amateur and professional astronomers are invited to provide observations of three comets that will make close approaches to Earth over the next two years. ...
The three comets are 41P/Tuttle-Giacobini-Kresak, 45P/Honda-Mrkos-Pajdusakova, and 46P/Wirtanen. The comets will pass by Earth at distances ranging from 0.08 AU to 0.15 AU. AU or Astronomical Unit is the distance from the Sun to Earth. Such close approaches of three comets within two years are rare and typically occur only once every few decades. ...
The team is seeking continuum (dust) images as well as gas images with good signal-to-noise.
