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. ≈ 2.1 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 184.1 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 1179 years in a starship at a tenth of light speed.
Distance. 118 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1908.

Saying hello

Say hello. A radio message and its reply would take 236 years round-trip.

Standing on it

A year here. A full year lasts just 615 Earth days.

By the numbers

Mass. Roughly 3639× Earth's mass — about 11.5 Jupiters.
Temperature. A frigid -54°C — colder than dry ice.

How we found it

Discovery. Found by La Silla Observatory using the radial velocity method.

About HD 7199 b

HD 7199 b is a rare exoplanet. It lies about 117.9 light-years from Earth, has an equilibrium temperature near 219 K, weighs about 3,639.14 Earth masses and completes an orbit every 615 days.

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

How to see it

Like any astronomical target, HD 7199 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 7199 b is a rare exoplanet

HD 7199 b scores 35 points on Spacedle's rarity scale, which places it in the rare tier. Another 11 points would lift it into a rarer tier.

That score comes from 2 science badges — Confirmed exoplanet and In the habitable zone — 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.
