Trivia

What it actually is

  • Crowded system. One of at least 2 planets orbiting its star.

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 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.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 23 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 2 million years even at the Parker Solar Probe's 192 km/s.

About Kepler-97 c

Kepler-97 c is an uncommon exoplanet. It lies about 1,307.6 light-years from Earth, shines at apparent magnitude 12.99, weighs about 344 Earth masses and completes an orbit every 789 days.

One of at least 2 planets orbiting its star.

How to see it

At apparent magnitude 12.99, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, Kepler-97 c 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-97 c is an uncommon exoplanet

Kepler-97 c scores 25 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 9 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Distant (over 1,000 light-years), Multi-planet system 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.
