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. ≈ 38.8 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 3.4 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 22.1 thousand years in a starship at a tenth of light speed.
  • Distance. 2207 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 4413 years round-trip.

Standing on it

  • A year here. A full year lasts just 482 Earth days.

By the numbers

  • Size. About 12.4× the width of Earth.
  • Volume. About 1907 Earths could fit inside it.
  • Mass. Roughly 3379× Earth's mass — about 10.6 Jupiters.
  • Your weight. You'd weigh about 22.0× your Earth weight standing here.
  • Density. Denser than solid iron.
  • Temperature. Around 878°C — hotter than a self-cleaning oven.

How we found it

  • Discovery. Found by McDonald Observatory using the radial velocity method.

About HD 95127 b

HD 95127 b is an epic exoplanet. It lies about 2,206.7 light-years from Earth, has an equilibrium temperature near 1,151 K, spans roughly 12.4 Earth radii and weighs about 3,378.53 Earth masses.

Packed denser than solid iron.

How to see it

Like any astronomical target, HD 95127 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 HD 95127 b is an epic exoplanet

HD 95127 b scores 47 points on Spacedle's rarity scale, which places it in the epic tier. Another 21 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, 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.
