Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 15.6 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 1.4 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 8879 years in a starship at a tenth of light speed.
- Distance. 888 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1138.
Saying hello
- Say hello. A radio message and its reply would take 1776 years round-trip.
Standing on it
- A year here. A full year lasts just 29 Earth days.
By the numbers
- Size. About 3.7× the width of Earth.
- Volume. About 51.1 Earths could fit inside it.
- Mass. About 13.3× the mass of Earth.
- Your weight. You'd weigh about 1.0× your Earth weight standing here.
- Temperature. Around 860°C — hotter than a self-cleaning oven.
How we found it
- Discovery. Found by Transiting Exoplanet Survey Satellite (TESS) using the transit method.

How to see it
Like any astronomical target, HD 56414 b 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 HD 56414 b is an uncommon exoplanet
HD 56414 b scores 31 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 2 points would lift it into a rarer tier.
That score comes from 5 science badges — Confirmed exoplanet, Sub-Neptune, Eccentric orbit, Blasted by starlight and Found by TESS — 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.
