Trivia

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 22.7 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 2 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 12.9 thousand years in a starship at a tenth of light speed.
Distance. 1293 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 733.

Saying hello

Say hello. A radio message and its reply would take 2585 years round-trip.

Standing on it

A year here. A full year lasts just 406 Earth days.

By the numbers

Size. About 13.4× the width of Earth.
Volume. About 2406 Earths could fit inside it.
Mass. Roughly 604× Earth's mass — about 1.9 Jupiters.
Your weight. You'd weigh about 3.4× your Earth weight standing here.
Temperature. A scorching 396°C on average.

How we found it

Discovery. Found by Kepler using the eclipse timing variations method.

Cosmic context

Crowded system. One of at least 3 planets orbiting its star.

Why 2MASS J19383260+4603591 b is an uncommon exoplanet

2MASS J19383260+4603591 b scores 28 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 5 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Gas giant, Multi-planet system, 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.
