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. Lighter than Neptune — a puffed-up ball of hydrogen and helium with no surface anywhere on it to stand on.

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.
  • 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 29.9 Earth days.
  • Starlight here. It receives about 33.5 times as much starlight as Earth gets from the Sun.

By the numbers

  • Size. About 3.4× the width of Earth.

About Kepler-1676 b

Kepler-1676 b is a common exoplanet. It shines at apparent magnitude 13.48, has an equilibrium temperature near 782 K, spans roughly 3.38 Earth radii and weighs about 11.3 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 13.48, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, Kepler-1676 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-1676 b is a common exoplanet

Kepler-1676 b scores 21 points on Spacedle's rarity scale, which places it in the common tier. Another 1 point would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Sub-Neptune, 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.
