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. ≈ 608.6 thousand years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 54.1 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 346 years in a starship at a tenth of light speed.
  • Distance. 34.6 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1991.

Saying hello

  • Say hello. A radio message and its reply would take 69.3 years round-trip.

Standing on it

  • A year here. A full year lasts just 23.1 Earth days.

By the numbers

  • Size. About 1.5× the width of Earth.
  • Mass. About 2.8× the mass of Earth.
  • Your weight. You'd weigh about 1.3× your Earth weight standing here.
  • Temperature. A surprisingly temperate 12°C average.

How we found it

  • Discovery. Found by Multiple Facilities using the radial velocity method.

Cosmic context

  • Crowded system. One of at least 5 planets orbiting its star.

About L 98-59 f

L 98-59 f is an epic exoplanet. It lies about 34.6 light-years from Earth, has an equilibrium temperature near 285 K, spans roughly 1.48 Earth radii and weighs about 2.8 Earth masses.

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

How to see it

Like any astronomical target, L 98-59 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 L 98-59 f is an epic exoplanet

L 98-59 f scores 63 points on Spacedle's rarity scale, which places it in the epic tier. Another 5 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, In the habitable zone, Super-Earth, 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.
