Trivia

What it actually is

  • Spectral class. Its spectrum reads B... — a blue-white B-type star, with a surface tens of thousands of degrees hot and a life measured in tens of millions of years.

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 10.9 you'll want a small backyard telescope, over in Cassiopeia.
  • 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 September — 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. ≈ 31.8 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 2.8 million years even at the Parker Solar Probe's 192 km/s.

About HIP 1727

HIP 1727 is a common star. It lies about 1,812 light-years from Earth, sits in the constellation Cas, shines at apparent magnitude 10.91 and has spectral type B....

Its spectrum reads B... — a blue-white B-type star, with a surface tens of thousands of degrees hot and a life measured in tens of millions of years.

How to see it

Look for HIP 1727 in the constellation Cas. At apparent magnitude 10.91, a small backyard telescope will bring it into view.

Like any astronomical target, HIP 1727 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 1727 is a common star

HIP 1727 scores 19 points on Spacedle's rarity scale, which places it in the common tier. Another 3 points would lift it into a rarer tier.

That score comes from 4 science badges — Star, Distant (over 1,000 light-years), Never sets (northern circumpolar) and Hot blue B-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.
