Trivia

Could we get there?

Verdict. Impossible with our current technology — and the next millennium of it.

Getting there

Aboard Voyager 1. ≈ 41.4 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 3.7 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 23.6 thousand years in a starship at a tenth of light speed.
Distance. 2357 light-years from Earth.

Look-back time

Look-back time. Its light left before the last ice age ended.

Saying hello

Say hello. A radio message and its reply would take 4715 years round-trip.

Standing on it

A year here. A full year lasts just 7.9 Earth days.

By the numbers

Size. About 12.9× the width of Earth.
Volume. About 2142 Earths could fit inside it.
Mass. Roughly 137× Earth's mass — about 0.4 Jupiters.
Your weight. You'd weigh about 0.8× your Earth weight standing here.
Density. Less dense than water — drop it in a big enough ocean and it would float.
Temperature. Around 755°C — hotter than a self-cleaning oven.

How we found it

Discovery. Found by Kepler using the transit method.

About Kepler-422 b

Kepler-422 b is an uncommon exoplanet. It lies about 2,357.4 light-years from Earth, has an equilibrium temperature near 1,028 K, spans roughly 12.89 Earth radii and weighs about 136.66 Earth masses.

About 12.9× the width of Earth.

How to see it

Like any astronomical target, Kepler-422 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 Kepler-422 b is an uncommon exoplanet

Kepler-422 b scores 32 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 1 point would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Found by Kepler and Distant (>1000 ly) — 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.
