Trivia

Could we get there?

  • Verdict. Impossible with our current technology — and the next millennium of it.

Getting there

  • Aboard Voyager 1. ≈ 35.2 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 3.1 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 20 thousand years in a starship at a tenth of light speed.
  • Distance. 2001 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 25.

Saying hello

  • Say hello. A radio message and its reply would take 4001 years round-trip.

Standing on it

  • A year here. A full year lasts just 193 Earth days.

By the numbers

  • Size. About 12.7× the width of Earth.
  • Volume. About 2048 Earths could fit inside it.
  • Mass. Roughly 1939× Earth's mass — about 6.1 Jupiters.
  • Your weight. You'd weigh about 12.0× your Earth weight standing here.
  • Temperature. Around 605°C — hotter than a self-cleaning oven.

How we found it

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

How to see it

Like any astronomical target, TYC 0434-04538-1 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 TYC 0434-04538-1 b is a common exoplanet

TYC 0434-04538-1 b 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 3 science badges — Confirmed exoplanet, Gas giant and Distant (>1000 ly) — 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.
