Trivia

What it actually is

  • Spectral class. Its spectrum reads F5II(R) — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
  • Where it is in life. It is a bright giant, well on its way to the largest stars there are.
  • 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 9.4 you'll want a small backyard telescope, over in Canis Major.
  • 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 January — that's when to go looking.

Could we get there?

  • Verdict. Impossible with our current technology — and the next millennium of it.

About HIP 36125

HIP 36125 is an uncommon variable star. It lies about 1,212.5 light-years from Earth, sits in the constellation CMa, shines at apparent magnitude 9.39 and has spectral type F5II(R).

Its spectrum reads F5II(R) — an F-type star — a little hotter, whiter and shorter-lived than the Sun.

How to see it

Look for HIP 36125 in the constellation CMa. At apparent magnitude 9.39, a small backyard telescope will bring it into view.

Like any astronomical target, HIP 36125 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 HIP 36125 is an uncommon variable star

HIP 36125 scores 33 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 1 point would lift it into a rarer tier.

That score comes from 6 science badges — Variable star, Distant (over 1,000 light-years), Yellow-white F-type star, Bright giant, Gently 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.
