Trivia

What makes it special

  • Goldilocks zone. Sits where it's neither too hot nor too cold — liquid water could exist.
  • 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. ≈ 5.1 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 453 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 2901 years in a starship at a tenth of light speed.
  • Distance. 290 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1736.

Saying hello

  • Say hello. A radio message and its reply would take 580 years round-trip.

Standing on it

  • A year here. A full year lasts just 571 Earth days.

By the numbers

  • Size. About 12.5× the width of Earth.
  • Volume. About 1953 Earths could fit inside it.
  • Mass. Roughly 2800× Earth's mass — about 8.8 Jupiters.
  • Your weight. You'd weigh about 17.9× your Earth weight standing here.
  • Density. Denser than solid iron.
  • Temperature. A frigid -24°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 TOI-1736 c

TOI-1736 c is an epic exoplanet. It lies about 290.1 light-years from Earth, has an equilibrium temperature near 249 K, spans roughly 12.5 Earth radii and weighs about 2,800 Earth masses.

Sits where it's neither too hot nor too cold — liquid water could exist.

How to see it

Like any astronomical target, TOI-1736 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 TOI-1736 c is an epic exoplanet

TOI-1736 c scores 63 points on Spacedle's rarity scale, which places it in the epic tier. Another 5 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, In the habitable zone, Gas giant, 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.
