Trivia

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 18.4 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 1.6 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 10.5 thousand years in a starship at a tenth of light speed.
Distance. 1048 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 978.

Saying hello

Say hello. A radio message and its reply would take 2096 years round-trip.

Standing on it

A year here. A full year lasts just 35.7 Earth days.

By the numbers

Size. About 3.9× the width of Earth.
Volume. About 61.2 Earths could fit inside it.
Mass. About 10.2× the mass of Earth.
Your weight. You'd weigh about 0.7× your Earth weight standing here.
Density. Less dense than water — drop it in a big enough ocean and it would float.
Temperature. Around 479°C — hotter than a self-cleaning oven.

How we found it

Discovery. Found by K2 using the transit method.

Cosmic context

Crowded system. One of at least 3 planets orbiting its star.

One of at least 3 planets orbiting its star.

How to see it

Like any astronomical target, EPIC 249893012 d 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 EPIC 249893012 d is an uncommon exoplanet

EPIC 249893012 d scores 26 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 7 points would lift it into a rarer tier.

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