Watching Comet Leonard from all angles

The ESA/NASA Solar Orbiter spacecraft flew through the tail of Comet C/2021 A1 Leonard in December 2021, collecting images and in-situ solar wind and particle data. At the same time, SOHO (ESA/NASA), Parker Solar Probe (NASA) and STEREO-A (NASA) were also watching the comet’s evolution from other angles.

The graphic shows the approximate relative positions of the planets, comet and spacecraft on 17 December 2021 and is not to scale. Very approximate fields of view are indicated for selected instruments: SoloHI on Solar Orbiter and SECCHI on STEREO-A.
