Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 13 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 1.2 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 7386 years in a starship at a tenth of light speed.
  • Distance. 739 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1287.

Saying hello

  • Say hello. A radio message and its reply would take 1477 years round-trip.

Standing on it

  • A year here. A full year lasts just 8 Earth days.

By the numbers

  • Size. About 3.1× the width of Earth.
  • Volume. About 29.6 Earths could fit inside it.
  • Mass. About 9.8× the mass of Earth.
  • Your weight. You'd weigh about 1.0× your Earth weight standing here.

How we found it

  • Discovery. Found by Transiting Exoplanet Survey Satellite (TESS) using the transit method.

Why TIC 154870955 b is a trash exoplanet

TIC 154870955 b scores 14 points on Spacedle's rarity scale, which places it in the trash tier. Another 1 point would lift it into a rarer tier.

That score comes from 3 science badges — Confirmed exoplanet, Sub-Neptune 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.
