Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 8 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 714.1 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 4574 years in a starship at a tenth of light speed.
- Distance. 457 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1569.
Saying hello
- Say hello. A radio message and its reply would take 915 years round-trip.
Standing on it
- A year here. A full year lasts just 3.8 Earth days.
By the numbers
- Size. About 11.5× the width of Earth.
- Volume. About 1512 Earths could fit inside it.
- Mass. Roughly 118× Earth's mass — about 0.4 Jupiters.
- Your weight. You'd weigh about 0.9× your Earth weight standing here.
- Density. Less dense than water — drop it in a big enough ocean and it would float.
- Temperature. A scorching 314°C on average.
How we found it
- Discovery. Found by HATSouth using the transit method.

How to see it
Like any astronomical target, HATS-71 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 HATS-71 b is a trash exoplanet
HATS-71 b scores 9 points on Spacedle's rarity scale, which places it in the trash tier. Another 6 points would lift it into a rarer tier.
That score comes from 2 science badges — Confirmed exoplanet and Gas giant — 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.
