Trivia

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.
At 10% light speed. ≈ 13.1 thousand years in a starship at a tenth of light speed.
Distance. 1308 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 718.

Saying hello

Say hello. A radio message and its reply would take 2615 years round-trip.

Standing on it

A year here. A full year lasts about 2.2 Earth years.

By the numbers

Mass. Roughly 344× Earth's mass — about 1.1 Jupiters.

How we found it

Discovery. Found by W. M. Keck Observatory using the radial velocity method.

Cosmic context

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

About Kepler-97 c

Kepler-97 c is a common exoplanet. It lies about 1,307.6 light-years from Earth, weighs about 344 Earth masses, completes an orbit every 789 days and belongs to a system of 2 known planets.

One of at least 2 planets orbiting its star.

How to see it

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 a common exoplanet

Kepler-97 c scores 21 points on Spacedle's rarity scale, which places it in the common tier. Another 3 points would lift it into a rarer tier.

That score comes from 3 science badges — Confirmed exoplanet, Multi-planet system and Distant (>1000 ly) — 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.
