Trivia

What it actually is

  • What it is made of. Its density says rock, though lighter than Earth's mix: probably less iron, or a thick shell of water and ice over the top.

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 10.4 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 June — that's when to go looking.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 6.9 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 616.9 thousand years even at the Parker Solar Probe's 192 km/s.

About TOI-4465 b

TOI-4465 b is a common exoplanet. It lies about 395.1 light-years from Earth, shines at apparent magnitude 10.43, has spectral type G V and has an equilibrium temperature near 427 K.

Its density says rock, though lighter than Earth's mix: probably less iron, or a thick shell of water and ice over the top.

How to see it

At apparent magnitude 10.43, a small backyard telescope will bring it into view.

Like any astronomical target, TOI-4465 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 TOI-4465 b is a common exoplanet

TOI-4465 b scores 21 points on Spacedle's rarity scale, which places it in the common tier. Another 1 point would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Found by TESS and Orbits a Sun-like star — 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.
