Trivia

What makes it special

Goldilocks zone. Sits where it's neither too hot nor too cold — liquid water could exist.
Packed system. Crammed into a system of five or more planets.

Could we get there?

Verdict. Hopelessly far for any craft humanity can build today.

Getting there

Aboard Voyager 1. ≈ 3.6 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 319.3 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 2045 years in a starship at a tenth of light speed.
Distance. 204 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1822.

Saying hello

Say hello. A radio message and its reply would take 409 years round-trip.

Standing on it

A year here. A full year lasts just 15.2 Earth days.

By the numbers

Size. About 2.4× the width of Earth.
Volume. About 14.1 Earths could fit inside it.
Mass. About 5.6× the mass of Earth.
Your weight. You'd weigh about 1.0× your Earth weight standing here.
Temperature. A scorching 248°C on average.

How we found it

Discovery. Found by Multiple Observatories using the transit method.

Cosmic context

Crowded system. One of at least 6 planets orbiting its star.

About TOI-178 f

TOI-178 f is an epic exoplanet. It lies about 204.5 light-years from Earth, has an equilibrium temperature near 521 K, spans roughly 2.42 Earth radii and weighs about 5.63 Earth masses.

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

How to see it

Like any astronomical target, TOI-178 f 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 TOI-178 f is an epic exoplanet

TOI-178 f scores 60 points on Spacedle's rarity scale, which places it in the epic tier. Another 8 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, In the habitable zone, Sub-Neptune, Multi-planet system and Richly packed system — 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.
