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. ≈ 8.5 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 758.5 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 4858 years in a starship at a tenth of light speed.
Distance. 486 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1540.

Saying hello

Say hello. A radio message and its reply would take 972 years round-trip.

Standing on it

A year here. A full year lasts about 7.2 Earth years.

By the numbers

Size. About 13.1× the width of Earth.
Volume. About 2248 Earths could fit inside it.
Mass. Roughly 1052× Earth's mass — about 3.3 Jupiters.
Your weight. You'd weigh about 6.1× your Earth weight standing here.
Temperature. A frigid -64°C — colder than dry ice.

How we found it

Discovery. Found by W. M. Keck Observatory using the radial velocity method.

About HD 13167 b

HD 13167 b is an epic exoplanet. It lies about 485.8 light-years from Earth, has an equilibrium temperature near 209 K, spans roughly 13.1 Earth radii and weighs about 1,052.02 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 13167 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 13167 b is an epic exoplanet

HD 13167 b scores 48 points on Spacedle's rarity scale, which places it in the epic tier. Another 20 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, In the habitable zone, Gas giant and Eccentric orbit — 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.
