Trivia

What makes it special

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

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 6 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 535.5 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 3430 years in a starship at a tenth of light speed.
  • Distance. 343 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1683.

Saying hello

  • Say hello. A radio message and its reply would take 686 years round-trip.

Standing on it

  • A year here. A full year lasts about 4.2 Earth years.

By the numbers

  • Size. About 13.6× the width of Earth.
  • Volume. About 2515 Earths could fit inside it.
  • Mass. Roughly 474× Earth's mass — about 1.5 Jupiters.
  • Your weight. You'd weigh about 2.6× your Earth weight standing here.
  • Temperature. A frigid -60°C — colder than dry ice.

How we found it

  • Discovery. Found by Roque de los Muchachos Observatory using the radial velocity method.

About HD 132563 b

HD 132563 b is a rare exoplanet. It lies about 343 light-years from Earth, has an equilibrium temperature near 213 K, spans roughly 13.6 Earth radii and weighs about 473.55 Earth masses.

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

How to see it

Like any astronomical target, HD 132563 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 132563 b is a rare exoplanet

HD 132563 b scores 39 points on Spacedle's rarity scale, which places it in the rare tier. Another 7 points would lift it into a rarer tier.

That score comes from 3 science badges — Confirmed exoplanet, In the habitable zone 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.
