Trivia

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.

Find it in the sky

  • How to spot it. At magnitude 15.6 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.
  • Best time of year. It stands highest in the middle of the night around July — that's when to go looking.

Standing on it

  • A year here. A full year lasts just 2.8 Earth days.
  • Eternal day. One side bakes in endless daylight while the other freezes in permanent night, with a ring of perpetual twilight in between.
  • Starlight here. It receives about 298 times as much starlight as Earth gets from the Sun.

About Kepler-1813 b

Kepler-1813 b is an uncommon exoplanet. It shines at apparent magnitude 15.64, has an equilibrium temperature near 1,059 K, spans roughly 1.41 Earth radii and weighs about 2.58 Earth masses.

It orbits closer to its star than Mercury does to the Sun, completing a lap in less time than Mercury takes.

How to see it

At apparent magnitude 15.64, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, Kepler-1813 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-1813 b is an uncommon exoplanet

Kepler-1813 b scores 26 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 8 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Super-Earth, Tidally locked and Found by Kepler — 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.
