Trivia

What it actually is

  • Spectral class. Its spectrum reads F3V — an F-type star — a little hotter, whiter and shorter-lived than the 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. 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 9.3 you'll want a small backyard telescope, over in Dorado.
  • Southern sky. It rides the southern half of the sky — an easier target the further south you are.
  • Best time of year. It stands highest in the middle of the night around December — 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. ≈ 18.7 million years at Voyager 1's speed (17 km/s).

About HD 30804

HD 30804 is a trash star. It lies about 1,065.9 light-years from Earth, sits in the constellation Dor, shines at apparent magnitude 9.3 and has spectral type F3V.

Its spectrum reads F3V — an F-type star — a little hotter, whiter and shorter-lived than the Sun.

How to see it

Look for HD 30804 in the constellation Dor. At apparent magnitude 9.3, a small backyard telescope will bring it into view.

Like any astronomical target, HD 30804 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 HD 30804 is a trash star

HD 30804 scores 14 points on Spacedle's rarity scale, which places it in the trash tier. Another 1 point would lift it into a rarer tier.

That score comes from 4 science badges — Star, Distant (over 1,000 light-years), Yellow-white F-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.
