Trivia
What it actually is
- Crowded system. One of at least 2 planets orbiting its star.
Sense of scale
- In perspective. Far away by human standards, yet still a local address inside the Milky Way's spiral arms.
Find it in the sky
- How to spot it. At magnitude 16.8 it is far too faint for the eye: this one belongs to cameras and long exposures.
- Southern sky. It rides the southern half of the sky — an easier target the further south you are.
- Best time of year. It stands highest in the middle of the night around November — that's when to go looking.
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 13.7 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 1.2 million years even at the Parker Solar Probe's 192 km/s.

How to see it
At apparent magnitude 16.78, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, UZ For b is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.
Why UZ For b is a rare exoplanet
UZ For b scores 35 points on Spacedle's rarity scale, which places it in the rare tier. Another 15 points would lift it into a rarer tier.
That score comes from 4 science badges — Confirmed exoplanet, Long-period world, Multi-planet system and Circumbinary (orbits both stars) — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
