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. ≈ 4.1 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 362 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 2319 years in a starship at a tenth of light speed.
Distance. 232 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1794.

Saying hello

Say hello. A radio message and its reply would take 464 years round-trip.

Standing on it

A year here. A full year lasts about 3.2 Earth years.

By the numbers

Size. About 12.3× the width of Earth.
Volume. About 1861 Earths could fit inside it.
Mass. Roughly 4704× Earth's mass — about 14.8 Jupiters.
Your weight. You'd weigh about 31.1× your Earth weight standing here.
Density. Denser than solid iron.
Temperature. A frigid -41°C — colder than dry ice.

How we found it

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

About HD 175167 b

HD 175167 b is an epic exoplanet. It lies about 231.9 light-years from Earth, has an equilibrium temperature near 232 K, spans roughly 12.3 Earth radii and weighs about 4,703.86 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 175167 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 175167 b is an epic exoplanet

HD 175167 b scores 66 points on Spacedle's rarity scale, which places it in the epic tier. Another 2 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, In the habitable zone, Gas giant, Eccentric orbit and Denser than iron — 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.
