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. ≈ 1.8 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 156.3 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 1001 years in a starship at a tenth of light speed.
Distance. 100 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1926.

Saying hello

Say hello. A radio message and its reply would take 200 years round-trip.

Standing on it

A year here. A full year lasts just 159 Earth days.

By the numbers

Size. About 9.6× the width of Earth.
Volume. About 879 Earths could fit inside it.
Mass. Roughly 66.6× Earth's mass — about 0.2 Jupiters.
Your weight. You'd weigh about 0.7× your Earth weight standing here.
Density. Less dense than water — drop it in a big enough ocean and it would float.
Temperature. A surprisingly temperate 14°C average.

How we found it

Discovery. Found by Las Campanas Observatory using the radial velocity method.

About HD 8326 b

HD 8326 b is a rare exoplanet. It lies about 100.1 light-years from Earth, has an equilibrium temperature near 287 K, spans roughly 9.58 Earth radii and weighs about 66.6 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 8326 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 8326 b is a rare exoplanet

HD 8326 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.
