Trivia
What makes it special
- Heavyweight. Packed denser than solid iron.
Could we get there?
- Verdict. Impossible with our current technology — and the next millennium of it.
Getting there
- Aboard Voyager 1. ≈ 47 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 4.2 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 26.8 thousand years in a starship at a tenth of light speed.
- Distance. 2677 light-years from Earth.
Look-back time
- Look-back time. Its light left before the last ice age ended.
Saying hello
- Say hello. A radio message and its reply would take 5355 years round-trip.
Standing on it
- A year here. A full year lasts about 8.8 Earth years.
By the numbers
- Size. About 12.3× the width of Earth.
- Volume. About 1861 Earths could fit inside it.
- Mass. Roughly 4497× Earth's mass — about 14.2 Jupiters.
- Your weight. You'd weigh about 29.7× your Earth weight standing here.
- Density. Denser than solid iron.
- Temperature. A scorching 200°C on average.
How we found it
- Discovery. Found by Multiple Observatories using the eclipse timing variations method.

Why NSVS 14256825 b is a rare exoplanet
NSVS 14256825 b scores 37 points on Spacedle's rarity scale, which places it in the rare tier. Another 9 points would lift it into a rarer tier.
That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Denser than iron 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.
