Overview
- Hubble captured a 30 November ultraviolet image with WFC3 showing a coma about 120,000 kilometers across when the comet was roughly 286 million kilometers from Earth.
- ESA’s JUICE spacecraft recorded views in early November from about 66 million kilometers using several instruments and its navigation camera.
- Mission teams report post‑perihelion activity has intensified, with distinct plasma and dust tails visible in recent images.
- Closest approach to Earth is expected on 19 December at around 270 million kilometers, with Hubble set to keep tracking the comet for months.
- The solid nucleus remains unresolved and is estimated to be no larger than about 11 kilometers, as multiple space‑ and ground‑based observatories coordinate observations.
