Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 12.4 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 1.1 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 7078 years in a starship at a tenth of light speed.
  • Distance. 708 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1318.

Saying hello

  • Say hello. A radio message and its reply would take 1416 years round-trip.

Standing on it

  • A year here. A full year lasts just 6.2 Earth days.

By the numbers

  • Size. About 5.6× the width of Earth.
  • Volume. About 178 Earths could fit inside it.
  • Mass. About 27× the mass of Earth.
  • Your weight. You'd weigh about 0.9× your Earth weight standing here.
  • Density. Less dense than water — drop it in a big enough ocean and it would float.
  • Temperature. Around 777°C — hotter than a self-cleaning oven.

How we found it

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

Cosmic context

  • Crowded system. One of at least 2 planets orbiting its star.

One of at least 2 planets orbiting its star.

How to see it

Like any astronomical target, TIC 434398831 c 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 TIC 434398831 c is a common exoplanet

TIC 434398831 c scores 19 points on Spacedle's rarity scale, which places it in the common tier. Another 5 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Neptune-like, Multi-planet system 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.
