Trivia

What makes it special

Lava world. Its surface is likely an ocean of molten rock.

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 40.5 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 3.6 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 23 thousand years in a starship at a tenth of light speed.
Distance. 2303 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 4605 years round-trip.

Standing on it

A year here. A full year lasts just 2 Earth days.

By the numbers

Size. About 19.1× the width of Earth.
Volume. About 6919 Earths could fit inside it.
Mass. Roughly 598× Earth's mass — about 1.9 Jupiters.
Your weight. You'd weigh about 1.6× your Earth weight standing here.
Density. Less dense than water — drop it in a big enough ocean and it would float.
Temperature. Around 2053 K — hot enough to vaporise iron.

How we found it

Discovery. Found by Qatar using the transit method.

About Qatar-7 b

Qatar-7 b is an epic exoplanet. It lies about 2,302.6 light-years from Earth, has an equilibrium temperature near 2,053 K, spans roughly 19.06 Earth radii and weighs about 597.52 Earth masses.

Its surface is likely an ocean of molten rock.

How to see it

Like any astronomical target, Qatar-7 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 Qatar-7 b is an epic exoplanet

Qatar-7 b scores 51 points on Spacedle's rarity scale, which places it in the epic tier. Another 17 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Lava world, Blasted by starlight 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.
