Trivia

What it actually is

  • Spectral class. Its spectrum reads G2III — a G-type star: the very same spectral class as our own Sun.
  • Where it is in life. It is a giant. It has already exhausted its core hydrogen and swollen up enormously in response.

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 4.4 you can see it with your own eyes from a dark site, over in Cepheus.
  • 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 September — 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. ≈ 4.3 million years at Voyager 1's speed (17 km/s).

33Pi Cep is an uncommon star. It lies about 246.7 light-years from Earth, sits in the constellation Cep, shines at apparent magnitude 4.41 and has spectral type G2III.

Its spectrum reads G2III — a G-type star: the very same spectral class as our own Sun.

How to see it

Look for 33Pi Cep in the constellation Cep. At apparent magnitude 4.41, it can be glimpsed with the unaided eye under dark skies.

Like any astronomical target, 33Pi Cep 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 33Pi Cep is an uncommon star

33Pi Cep scores 29 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 5 points would lift it into a rarer tier.

That score comes from 5 science badges — Star, Naked-eye visible, Never sets (northern circumpolar), Sun-like G-type star and Giant 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.
