Trivia

What it actually is

  • Spectral class. Its spectrum reads sdG3: — a G-type star: the very same spectral class as our own Sun.
  • Where it is in life. It is a subdwarf: an old, metal-poor star from the galaxy's early days, a little smaller and fainter than a main-sequence star of the same colour.

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 11.4 you'll want a small backyard telescope, over in Leo.
  • Seen from everywhere. It sits almost on the celestial equator, so it can be seen from essentially anywhere on Earth.
  • Best time of year. It stands highest in the middle of the night around March — 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. ≈ 3.7 million years at Voyager 1's speed (17 km/s).

Why HIP 54639 is a trash star

HIP 54639 scores 14 points on Spacedle's rarity scale, which places it in the trash tier. Another 1 point would lift it into a rarer tier.

That score comes from 3 science badges — Star, On the zodiac and Sun-like G-type 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.
