Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 13.8 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 1.2 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 7851 years in a starship at a tenth of light speed.
  • Distance. 785 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1241.

Saying hello

  • Say hello. A radio message and its reply would take 1570 years round-trip.

Standing on it

  • A year here. A full year lasts just 3.2 Earth days.

By the numbers

  • Size. About 6.3× the width of Earth.
  • Volume. About 251 Earths could fit inside it.
  • Mass. About 38.1× the mass of Earth.
  • Your weight. You'd weigh about 1.0× your Earth weight standing here.
  • Density. Less dense than water — drop it in a big enough ocean and it would float.
  • Temperature. Around 811°C — hotter than a self-cleaning oven.

How we found it

  • Discovery. Found by HATSouth using the transit method.

About HATS-7 b

HATS-7 b is a common exoplanet. It lies about 785.1 light-years from Earth, has an equilibrium temperature near 1,084 K, spans roughly 6.31 Earth radii and weighs about 38.14 Earth masses.

About 6.3× the width of Earth.

How to see it

Like any astronomical target, HATS-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 HATS-7 b is a common exoplanet

HATS-7 b scores 19 points on Spacedle's rarity scale, which places it in the common tier. Another 5 points would lift it into a rarer tier.

That score comes from 3 science badges — Confirmed exoplanet, Gas giant and Hot Jupiter — 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.
