Trivia

What makes it special

  • Ultra-hot Jupiter. So hot that iron vaporises and rains back down as molten metal.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 83.6 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 7.4 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 47.6 thousand years in a starship at a tenth of light speed.
  • Distance. 4758 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 9516 years round-trip.

Standing on it

  • A year here. A full year lasts just 1.9 Earth days.

By the numbers

  • Size. About 15.5× the width of Earth.
  • Volume. About 3733 Earths could fit inside it.
  • Mass. Roughly 4100× Earth's mass — about 12.9 Jupiters.
  • Your weight. You'd weigh about 17.0× your Earth weight standing here.
  • Temperature. Around 2730 K — hot enough to vaporise iron.

How we found it

  • Discovery. Found by HATSouth using the transit method.

About HATS-70 b

HATS-70 b is an epic exoplanet. It lies about 4,758.1 light-years from Earth, has an equilibrium temperature near 2,730 K, spans roughly 15.51 Earth radii and weighs about 4,100.01 Earth masses.

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

How to see it

Like any astronomical target, HATS-70 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-70 b is an epic exoplanet

HATS-70 b scores 63 points on Spacedle's rarity scale, which places it in the epic tier. Another 5 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Ultra-hot Jupiter, 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.
