Trivia

What it actually is

  • Spectral class. Its spectrum reads Sevar — an S-type giant, its atmosphere laced with zirconium dredged up from the fusion going on below.
  • It changes. This star does not hold still: its brightness rises and falls on a rhythm of hours, days or years, either pulsing in size or being eclipsed by a companion.

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 9.8 you'll want a small backyard telescope, over in Monoceros.
  • Seen from everywhere. It sits almost on the celestial equator, so it can be seen from essentially anywhere on Earth.
  • 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. ≈ 43.8 million years at Voyager 1's speed (17 km/s).

About HD 44544

HD 44544 is an epic variable star. It lies about 2,489.7 light-years from Earth, sits in the constellation Mon, shines at apparent magnitude 9.76 and has spectral type Sevar.

Its spectrum reads Sevar — an S-type giant, its atmosphere laced with zirconium dredged up from the fusion going on below.

How to see it

Look for HD 44544 in the constellation Mon. At apparent magnitude 9.76, a small backyard telescope will bring it into view.

Like any astronomical target, HD 44544 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 44544 is an epic variable star

HD 44544 scores 52 points on Spacedle's rarity scale, which places it in the epic tier. Another 26 points would lift it into a rarer tier.

That score comes from 6 science badges — Variable star, Distant (over 1,000 light-years), S-type star (zirconium giant), Deep red star, Strongly variable and A named variable 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.
