Trivia

What makes it special

Goldilocks zone. Sits where it's neither too hot nor too cold — liquid water could exist.

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 41.8 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 3.7 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 23.8 thousand years in a starship at a tenth of light speed.
Distance. 2376 light-years from Earth.

Look-back time

Look-back time. Its light left before the last ice age ended.

Saying hello

Say hello. A radio message and its reply would take 4752 years round-trip.

Standing on it

A year here. A full year lasts just 328 Earth days.

By the numbers

Size. About 11.6× the width of Earth.
Volume. About 1552 Earths could fit inside it.
Mass. Roughly 2129× Earth's mass — about 6.7 Jupiters.
Your weight. You'd weigh about 15.9× your Earth weight standing here.
Temperature. A surprisingly temperate -22°C average.

How we found it

Discovery. Found by Kepler using the transit method.

Cosmic context

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

About Kepler-553 c

Kepler-553 c is an epic exoplanet. It lies about 2,376.1 light-years from Earth, has an equilibrium temperature near 251 K, spans roughly 11.58 Earth radii and weighs about 2,129.45 Earth masses.

Sits where it's neither too hot nor too cold — liquid water could exist.

How to see it

Like any astronomical target, Kepler-553 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-553 c is an epic exoplanet

Kepler-553 c scores 58 points on Spacedle's rarity scale, which places it in the epic tier. Another 10 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, In the habitable zone, Gas giant, Multi-planet system, Found by Kepler 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.
