Trivia

What it actually is

  • What it is made of. Lighter than Neptune — a puffed-up ball of hydrogen and helium with no surface anywhere on it to stand on.

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 22.8 it is far too faint for the eye: this one belongs to cameras and long exposures.
  • Southern sky. It rides the southern half of the sky — an easier target the further south 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. Impossible with our current technology — and the next millennium of it.

Getting there

  • Aboard Voyager 1. ≈ 235 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 20.9 million years even at the Parker Solar Probe's 192 km/s.

About OGLE-2005-BLG-169L b

OGLE-2005-BLG-169L b is an uncommon exoplanet. It lies about 13,372.4 light-years from Earth, shines at apparent magnitude 22.78, has spectral type K5 and spans roughly 3.84 Earth radii.

Lighter than Neptune — a puffed-up ball of hydrogen and helium with no surface anywhere on it to stand on.

How to see it

At apparent magnitude 22.78, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, OGLE-2005-BLG-169L 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 OGLE-2005-BLG-169L b is an uncommon exoplanet

OGLE-2005-BLG-169L b scores 28 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 6 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Distant (over 1,000 light-years), Sub-Neptune and Found by microlensing — 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.
