Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 10.9 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 969.8 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 6211 years in a starship at a tenth of light speed.
- Distance. 621 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1405.
Saying hello
- Say hello. A radio message and its reply would take 1242 years round-trip.
Standing on it
- A year here. A full year lasts just 35.5 Earth days.
By the numbers
- Size. About 9.2× the width of Earth.
- Volume. About 768 Earths could fit inside it.
- Mass. Roughly 109× Earth's mass — about 0.3 Jupiters.
- Your weight. You'd weigh about 1.3× your Earth weight standing here.
- Density. Less dense than water — drop it in a big enough ocean and it would float.
- Temperature. A scorching 162°C on average.
How we found it
- Discovery. Found by Transiting Exoplanet Survey Satellite (TESS) using the transit method.

How to see it
Like any astronomical target, NGTS-11 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 NGTS-11 b is a trash exoplanet
NGTS-11 b scores 13 points on Spacedle's rarity scale, which places it in the trash tier. Another 2 points would lift it into a rarer tier.
That score comes from 3 science badges — Confirmed exoplanet, Gas giant and Found by TESS — 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.
