Trivia

What it actually is

  • Spectral class. Its spectrum reads G0 — a G-type star: the very same spectral class as our own Sun.
  • It changes. This star does not hold still: its brightness rises and falls on a rhythm of hours, days or years, either pulsing in size or being eclipsed by a companion.

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 10.5 you'll want a small backyard telescope, over in Ursa Major.
  • Never sets. So far north that from Britain, Canada or northern Europe it never dips below the horizon — it is up every clear night of the year.
  • 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. Impossible with our current technology — and the next millennium of it.

Getting there

  • Aboard Voyager 1. ≈ 22.9 million years at Voyager 1's speed (17 km/s).

About HIP 52892

HIP 52892 is an uncommon variable star. It lies about 1,304.6 light-years from Earth, sits in the constellation UMa, shines at apparent magnitude 10.51 and has spectral type G0.

Its spectrum reads G0 — a G-type star: the very same spectral class as our own Sun.

How to see it

Look for HIP 52892 in the constellation UMa. At apparent magnitude 10.51, a small backyard telescope will bring it into view.

Like any astronomical target, HIP 52892 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 HIP 52892 is an uncommon variable star

HIP 52892 scores 30 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 4 points would lift it into a rarer tier.

That score comes from 6 science badges — Variable star, Distant (over 1,000 light-years), Never sets (northern circumpolar), Sun-like G-type star, Gently variable and A named variable 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.
