Trivia

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 2.2 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 194.2 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 1244 years in a starship at a tenth of light speed.
Distance. 124 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1902.

Saying hello

Say hello. A radio message and its reply would take 249 years round-trip.

Standing on it

A year here. A full year lasts just 273 Earth days.

By the numbers

Size. About 13.6× the width of Earth.
Volume. About 2515 Earths could fit inside it.
Mass. Roughly 413× Earth's mass — about 1.3 Jupiters.
Your weight. You'd weigh about 2.2× your Earth weight standing here.
Density. Less dense than water — drop it in a big enough ocean and it would float.
Temperature. A frigid -70°C — colder than dry ice.

How we found it

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

Cosmic context

Wild orbit. Its highly elliptical path swings between scorching and frozen each lap.

About GJ 2126 b

GJ 2126 b is a common exoplanet. It lies about 124.4 light-years from Earth, has an equilibrium temperature near 203 K, spans roughly 13.6 Earth radii and weighs about 413.18 Earth masses.

Its highly elliptical path swings between scorching and frozen each lap.

How to see it

Like any astronomical target, GJ 2126 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 GJ 2126 b is a common exoplanet

GJ 2126 b scores 18 points on Spacedle's rarity scale, which places it in the common tier. Another 6 points would lift it into a rarer tier.

That score comes from 3 science badges — Confirmed exoplanet, 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.
