Trivia

What it actually is

  • Spectral class. Its spectrum reads A2IIIs — an A-type star: white-hot, typically about twice the Sun's mass, and the class most of the sky's famous bright stars belong to.
  • 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 4.6 you can see it with your own eyes from a dark site, over in Draco.
  • 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 July — 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 million years at Voyager 1's speed (17 km/s).

About 58Pi Dra

58Pi Dra is an uncommon star. It lies about 228.9 light-years from Earth, sits in the constellation Dra, shines at apparent magnitude 4.6 and has spectral type A2IIIs.

Its spectrum reads A2IIIs — an A-type star: white-hot, typically about twice the Sun's mass, and the class most of the sky's famous bright stars belong to.

How to see it

Look for 58Pi Dra in the constellation Dra. At apparent magnitude 4.6, it can be glimpsed with the unaided eye under dark skies.

Like any astronomical target, 58Pi Dra 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 58Pi Dra is an uncommon star

58Pi Dra scores 26 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 8 points would lift it into a rarer tier.

That score comes from 5 science badges — Star, Naked-eye visible, Never sets (northern circumpolar), White A-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.
