Trivia

What makes it special

Ultra-hot Jupiter. So hot that iron vaporises and rains back down as molten metal.
Heavyweight. Packed denser than solid iron.

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 15.4 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 1.4 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 8755 years in a starship at a tenth of light speed.
Distance. 876 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1150.

Saying hello

Say hello. A radio message and its reply would take 1751 years round-trip.

Standing on it

A year here. A full year lasts just 1.2 Earth days.

By the numbers

Size. About 12.4× the width of Earth.
Volume. About 1926 Earths could fit inside it.
Mass. Roughly 8654× Earth's mass — about 27.2 Jupiters.
Your weight. You'd weigh about 55.9× your Earth weight standing here.
Density. Denser than solid iron.
Temperature. Around 2361 K — hot enough to vaporise iron.

How we found it

Discovery. Found by KELT using the transit method.

About KELT-1 b

KELT-1 b is an anomaly exoplanet. It lies about 875.5 light-years from Earth, has an equilibrium temperature near 2,361 K, spans roughly 12.44 Earth radii and weighs about 8,654.15 Earth masses.

So hot that iron vaporises and rains back down as molten metal.

How to see it

Like any astronomical target, KELT-1 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 KELT-1 b is an anomaly exoplanet

KELT-1 b scores 71 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 24 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Ultra-hot Jupiter, Denser than iron and Blasted by starlight — 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.
