Trivia

What makes it special

  • Frozen world. A deep-frozen world far from its star's warmth.
  • 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. ≈ 3 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 270.5 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 1732 years in a starship at a tenth of light speed.
  • Distance. 173 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1853.

Saying hello

  • Say hello. A radio message and its reply would take 346 years round-trip.

Standing on it

  • A year here. A full year lasts about 205 Earth years.

By the numbers

  • Size. About 12× the width of Earth.
  • Volume. About 1728 Earths could fit inside it.
  • Mass. Roughly 7923× Earth's mass — about 24.9 Jupiters.
  • Your weight. You'd weigh about 55.0× your Earth weight standing here.
  • Density. Denser than solid iron.
  • Temperature. A frigid -214°C — colder than dry ice.

How we found it

  • Discovery. Found by Multiple Observatories using the radial velocity method.

Cosmic context

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

About HD 62364 c

HD 62364 c is an epic exoplanet. It lies about 173.2 light-years from Earth, has an equilibrium temperature near 59 K, spans roughly 12 Earth radii and weighs about 7,923.46 Earth masses.

A deep-frozen world far from its star's warmth.

How to see it

Like any astronomical target, HD 62364 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 62364 c is an epic exoplanet

HD 62364 c scores 60 points on Spacedle's rarity scale, which places it in the epic tier. Another 8 points would lift it into a rarer tier.

That score comes from 7 science badges — Confirmed exoplanet, Gas giant, Frozen world, Long-period world, Eccentric orbit, 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.
