Trivia
Could we get there?
- Verdict. Impossible with our current technology — and the next millennium of it.
Getting there
- Aboard Voyager 1. ≈ 28.9 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 2.6 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 16.5 thousand years in a starship at a tenth of light speed.
- Distance. 1647 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 379.
Saying hello
- Say hello. A radio message and its reply would take 3294 years round-trip.
Standing on it
- A year here. A full year lasts about 27.8 Earth years.
By the numbers
- Size. About 1.2× the width of Earth.
- Mass. About 2× the mass of Earth.
- Your weight. You'd weigh about 1.3× your Earth weight standing here.
How we found it
- Discovery. Found by Multiple Facilities using the pulsar timing method.

How to see it
Like any astronomical target, PSR B0329+54 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 PSR B0329+54 b is a rare exoplanet
PSR B0329+54 b scores 41 points on Spacedle's rarity scale, which places it in the rare tier. Another 5 points would lift it into a rarer tier.
That score comes from 4 science badges — Confirmed exoplanet, Earth-sized, Long-period world and Distant (>1000 ly) — 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.
