Trivia

What it actually is

  • Spectral class. Its spectrum reads G5V — a G-type star: the very same spectral class as our own Sun.
  • Where it is in life. It is on the main sequence, quietly fusing hydrogen in its core exactly as the Sun does.

Sense of scale

  • In perspective. Inside our stellar backyard: every radio broadcast humanity has ever made has already swept past it.

Find it in the sky

  • How to spot it. At magnitude 5.9 you can see it with your own eyes from a dark site, over in Taurus.
  • 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 November — 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. ≈ 970.8 thousand years at Voyager 1's speed (17 km/s).

About 39 Tau

39 Tau is an uncommon star. It lies about 55.2 light-years from Earth, sits in the constellation Tau, shines at apparent magnitude 5.9 and has spectral type G5V.

Its spectrum reads G5V — a G-type star: the very same spectral class as our own Sun.

How to see it

Look for 39 Tau in the constellation Tau. At apparent magnitude 5.9, it can be glimpsed with the unaided eye under dark skies.

Like any astronomical target, 39 Tau 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 39 Tau is an uncommon star

39 Tau scores 24 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 10 points would lift it into a rarer tier.

That score comes from 5 science badges — Star, Naked-eye visible, On the zodiac, Sun-like G-type star and Main-sequence 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.
