Trivia

What makes it special

  • Lava world. Its surface is likely an ocean of molten rock.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 11.4 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 1 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 6509 years in a starship at a tenth of light speed.
  • Distance. 651 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1375.

Saying hello

  • Say hello. A radio message and its reply would take 1302 years round-trip.

Standing on it

  • A year here. A full year lasts just 1.7 Earth days.

By the numbers

  • Size. About 11.4× the width of Earth.
  • Volume. About 1495 Earths could fit inside it.
  • Mass. Roughly 465× Earth's mass — about 1.5 Jupiters.
  • Your weight. You'd weigh about 3.6× your Earth weight standing here.
  • Temperature. Around 1441°C — hotter than a self-cleaning oven.

How we found it

  • Discovery. Found by Transiting Exoplanet Survey Satellite (TESS) using the transit method.

About TOI-564 b

TOI-564 b is a rare exoplanet. It lies about 650.9 light-years from Earth, has an equilibrium temperature near 1,714 K, spans roughly 11.43 Earth radii and weighs about 464.99 Earth masses.

Its surface is likely an ocean of molten rock.

How to see it

Like any astronomical target, TOI-564 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 TOI-564 b is a rare exoplanet

TOI-564 b scores 45 points on Spacedle's rarity scale, which places it in the rare tier. Another 1 point would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Lava world, Blasted by starlight and Found by TESS — 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.
