Trivia
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 6.1 it is just past naked-eye reach — ordinary binoculars will pull it in.
- Southern sky only. So far south it never rises for most of the northern hemisphere. To see it you'd have to travel to Chile, South Africa or Australia.
- Best time of year. It stands highest in the middle of the night around January — 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. ≈ 1.9 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 173.2 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 1109 years in a starship at a tenth of light speed.

How to see it
At apparent magnitude 6.11, it is an easy target for binoculars.
Like any astronomical target, HR 2562 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 HR 2562 b is a rare exoplanet
HR 2562 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, Gas giant, Hot Jupiter and Directly imaged — 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.
