Trivia

What makes it special

  • Heavyweight. Packed denser than solid iron.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 2.1 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 184.3 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 1180 years in a starship at a tenth of light speed.
  • Distance. 118 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1908.

Saying hello

  • Say hello. A radio message and its reply would take 236 years round-trip.

Standing on it

  • A year here. A full year lasts about 14.9 Earth years.

By the numbers

  • Size. About 12.1× the width of Earth.
  • Volume. About 1772 Earths could fit inside it.
  • Mass. Roughly 6300× Earth's mass — about 19.8 Jupiters.
  • Your weight. You'd weigh about 43.0× your Earth weight standing here.
  • Density. Denser than solid iron.
  • Temperature. A frigid -120°C — colder than dry ice.

How we found it

  • Discovery. Found by Haute-Provence Observatory using the radial velocity method.

Cosmic context

  • Crowded system. One of at least 2 planets orbiting its star.

About HD 113337 c

HD 113337 c is a rare exoplanet. It lies about 118 light-years from Earth, has an equilibrium temperature near 153 K, spans roughly 12.1 Earth radii and weighs about 6,299.68 Earth masses.

Packed denser than solid iron.

How to see it

Like any astronomical target, HD 113337 c 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 113337 c is a rare exoplanet

HD 113337 c scores 43 points on Spacedle's rarity scale, which places it in the rare tier. Another 3 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Gas giant, Long-period world, Denser than iron and Multi-planet system — 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.
