Trivia

What it actually is

  • What it is made of. Too light to be solid rock and too heavy to be all gas: most likely a deep global ocean or a thick steamy envelope over a rocky core.

Sense of scale

  • In perspective. Far away by human standards, yet still a local address inside the Milky Way's spiral arms.

Find it in the sky

  • How to spot it. At magnitude 9.9 you'll want a small backyard telescope.
  • Northern sky. It rides the northern half of the sky — an easier target the further north you are.
  • Best time of year. It stands highest in the middle of the night around November — that's when to go looking.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 28.1 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 2.5 million years even at the Parker Solar Probe's 192 km/s.

About TYC 3318-01333-1 b

TYC 3318-01333-1 b is a common exoplanet. It lies about 1,600.2 light-years from Earth, shines at apparent magnitude 9.9, has an equilibrium temperature near 470 K and spans roughly 13.1 Earth radii.

Too light to be solid rock and too heavy to be all gas: most likely a deep global ocean or a thick steamy envelope over a rocky core.

How to see it

At apparent magnitude 9.9, a small backyard telescope will bring it into view.

Like any astronomical target, TYC 3318-01333-1 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 3318-01333-1 b is a common exoplanet

TYC 3318-01333-1 b scores 15 points on Spacedle's rarity scale, which places it in the common tier. Another 7 points would lift it into a rarer tier.

That score comes from 3 science badges — Confirmed exoplanet, Distant (over 1,000 light-years) and Gas giant — 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.
