Trivia

What makes it special

  • Ultra-hot Jupiter. So hot that iron vaporises on the dayside, blows around to the night side and rains back down as molten metal.

What it actually is

  • Hugging its star. It orbits closer to its star than Mercury does to the Sun, completing a lap in less time than Mercury takes.
  • What it is made of. Its density says rock, though lighter than Earth's mix: probably less iron, or a thick shell of water and ice over the top.

Sense of scale

  • In perspective. Far away by human standards, yet still a local address inside the Milky Way's spiral arms.

Find it in the sky

  • How to spot it. At magnitude 9.8 you'll want a small backyard telescope.
  • Northern sky. It rides the northern half of the sky — an easier target the further north you are.
  • Best time of year. It stands highest in the middle of the night around July — that's when to go looking.

Could we get there?

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

About KOI-13 b

KOI-13 b is an anomaly exoplanet. It lies about 1,693.1 light-years from Earth, shines at apparent magnitude 9.79, has an equilibrium temperature near 2,550 K and spans roughly 16.95 Earth radii.

So hot that iron vaporises on the dayside, blows around to the night side and rains back down as molten metal.

How to see it

At apparent magnitude 9.79, a small backyard telescope will bring it into view.

Like any astronomical target, KOI-13 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 KOI-13 b is an anomaly exoplanet

KOI-13 b scores 84 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 36 points would lift it into a rarer tier.

That score comes from 9 science badges — Confirmed exoplanet, Distant (over 1,000 light-years), Gas giant, Ultra-hot Jupiter, Tidally locked, Blasted by starlight, Found by Kepler and Orbits a hot blue-white star — 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.
