Trivia

Could we get there?

  • Verdict. Hopelessly far for any craft humanity can build today.

Getting there

  • Aboard Voyager 1. ≈ 2.2 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 191.7 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 1228 years in a starship at a tenth of light speed.
  • Distance. 123 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1903.

Saying hello

  • Say hello. A radio message and its reply would take 246 years round-trip.

Standing on it

  • A year here. A full year lasts about 2.6 Earth years.

By the numbers

  • Size. About 10.3× the width of Earth.
  • Volume. About 1093 Earths could fit inside it.
  • Mass. Roughly 75.3× Earth's mass — about 0.2 Jupiters.
  • Your weight. You'd weigh about 0.7× your Earth weight standing here.
  • Density. Less dense than water — drop it in a big enough ocean and it would float.
  • Temperature. A frigid -75°C — colder than dry ice.

How we found it

  • Discovery. Found by La Silla Observatory using the radial velocity method.

About HD 126525 b

HD 126525 b is a trash exoplanet. It lies about 122.8 light-years from Earth, has an equilibrium temperature near 198 K, spans roughly 10.3 Earth radii and weighs about 75.33 Earth masses.

About 10.3× the width of Earth.

How to see it

Like any astronomical target, HD 126525 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 126525 b is a trash exoplanet

HD 126525 b scores 9 points on Spacedle's rarity scale, which places it in the trash tier. Another 6 points would lift it into a rarer tier.

That score comes from 2 science badges — Confirmed exoplanet and Gas giant — 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.
