The ISS appears as a very bright, fast-moving star — no telescope needed! It moves from horizon to horizon in ~6 minutes.

Near-Earth Objects passing within 7.5M km tonight. Data from NASA NeoWs API. ℹ️

Scanning NASA Database...

Notable comets currently in the inner solar system. Some are visible with binoculars or a small telescope.

🌠 C/2023 A3 Tsuchinshan-ATLAS Naked Eye

📐 Perihelion: Sep 27, 2024 · Closest approach: Oct 12, 2024

One of the brightest comets in decades — reached magnitude −4.9 at peak. Now fading but still a historic visitor. Expected to return in ~80,000 years.

🏎️ Speed: ~68 km/s 📡 Origin: Oort Cloud ⭐ Peak Mag: −4.9

🌠 12P/Pons-Brooks Binoculars

📐 Perihelion: Apr 21, 2024 · Period: ~71 years

The "Devil Comet" — famous for its cryo-volcanic outbursts that gave it distinctive horn-shaped coma. Last visible to the naked eye in 1954. Returns ~2095.

🏎️ Speed: ~44 km/s 📡 Short-period ⭐ Peak Mag: +4.0

🌠 67P/Churyumov-Gerasimenko Telescope

📐 Perihelion: ~Nov 2, 2021 · Period: ~6.5 years

The Rosetta Mission target. ESA's Rosetta spacecraft orbited it for 2 years and landed the Philae probe on its surface in 2014 — the first soft comet landing in history.

🏎️ Speed: ~34 km/s 📡 Jupiter-family 📏 Size: 4.3 × 2.6 km

🌠 C/2024 G3 (ATLAS) Jan 2025

📐 Perihelion: Jan 13, 2025 · Southern hemisphere favored

Reached potentially spectacular brightness (mag −2 to −3) near perihelion in January 2025, best seen from the southern hemisphere. Likely a dynamically new comet on its first inner solar system pass.

📡 Oort Cloud ⭐ Est. Peak: −3 🔭 Best: S. Hemisphere

How to read this chart

🚦 The Traffic Light System SUMMARY Row: Red means clouded over. Green means perfectly clear. Orange means mixed conditions.
CLOUD Rows: Pure white squares mean 0% clouds. Dark blue squares mean 100% cloud cover.

🌫️ How to Spot the Haze Look at the REL. HUMIDITY & DEW RISK rows. When humidity is high, moisture creates a thick, milky haze that scatters light and washes out faint stars. If these rows turn Red/Orange, expect poor transparency even if cloud cover is 0%.

💧 Telescope Dew Warning If the Dew Risk row is glowing red, water vapor will condense quickly. Glass lenses and mirrors will fog up and end your session if you don't use a dew heater or dew shield!
