What comet reached its perihelion around January 8, 2026, making it brightest for comet hunters?

Comet 24P/Schaumasse reached its perihelion, the point in its orbit closest to the Sun, around January 8, 2026. This celestial event is crucial for a comet's brightness, as the increased solar radiation causes its icy nucleus to sublimate, releasing gas and dust that form the visible coma and tail. While not a naked-eye object, 24P/Schaumasse became a standout telescopic target for observers in both the Northern and Southern Hemispheres during this period.

Discovered in 1911 by French astronomer Alexandre Schaumasse, this is a short-period, Jupiter-family comet, meaning its orbit is influenced by Jupiter's gravity and it returns to the inner solar system relatively frequently, approximately every 8.2 years. Its diameter is estimated to be around 2.6 kilometers, comparable to the size of Mount Everest. Comets, unlike planets, have highly elliptical orbits, leading to significant variations in their distance from the Sun.

The 2026 apparition of 24P/Schaumasse was particularly favorable for comet hunters due to its geometry relative to Earth. Even though its perihelion distance of about 1.184 astronomical units (AU) was farther than Earth's average distance from the Sun, the comet remained well-placed in the night sky, far from the Sun's position. This allowed for extended dark-sky observing windows, minimizing twilight interference and offering excellent conditions for both visual study and astrophotography. Its brightness peaked around magnitude 7.94 to 9.9, making it visible with a small telescope (Deals).
