Trivia

What makes it special

  • Earth-sized. Genuinely comparable to Earth in size. Worlds in this narrow band are the ones every next-generation telescope is being pointed at.
  • Ultra-hot Jupiter. So hot that iron vaporises on the dayside, blows around to the night side and rains back down as molten metal.

Hard to believe

  • A year in a day. Its entire year is over in 16.6 hours. Birthdays here would come round faster than meals.

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 13.5 it is far too faint for the eye: this one belongs to cameras and long exposures.
  • Northern sky. It rides the northern half of the sky — an easier target the further north you are.

About Kepler-1547 b

Kepler-1547 b is an anomaly exoplanet. It lies about 2,200.6 light-years from Earth, shines at apparent magnitude 13.46, has an equilibrium temperature near 3,186 K and spans roughly 0.9 Earth radii.

Genuinely comparable to Earth in size. Worlds in this narrow band are the ones every next-generation telescope is being pointed at.

How to see it

At apparent magnitude 13.46, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, Kepler-1547 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 Kepler-1547 b is an anomaly exoplanet

Kepler-1547 b scores 82 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 38 points would lift it into a rarer tier.

That score comes from 8 science badges — Confirmed exoplanet, Distant (over 1,000 light-years), Earth-sized, Ultra-hot Jupiter, Ultra-short period, Blasted by starlight, Found by Kepler and Orbits a Sun-like 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.
