Trivia

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 27.3 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 2.4 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 15.6 thousand years in a starship at a tenth of light speed.
Distance. 1555 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 471.

Saying hello

Say hello. A radio message and its reply would take 3111 years round-trip.

Standing on it

A year here. A full year lasts just 3.8 Earth days.

By the numbers

Size. About 1.2× the width of Earth.
Mass. About 2× the mass of Earth.
Your weight. You'd weigh about 1.3× your Earth weight standing here.

How we found it

Discovery. Found by K2 using the transit method.

Cosmic context

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

Why EPIC 201615463 c is a rare exoplanet

EPIC 201615463 c scores 37 points on Spacedle's rarity scale, which places it in the rare tier. Another 9 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Earth-sized, 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.
