Trivia

What it actually is

  • Spectral class. Its spectrum reads C7Iab — a carbon star, wrapped in so much soot that its light is filtered to a deep ruby red.
  • Where it is in life. It is a supergiant. Drop it where the Sun is and its surface would engulf the inner planets.
  • 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 5.4 you can see it with your own eyes from a dark site, over in Canes Venatici.
  • 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 April — that's when to go looking.

Could we get there?

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

About La Superba

La Superba is an anomaly variable star. It lies about 1,045.4 light-years from Earth, sits in the constellation CVn, shines at apparent magnitude 5.42 and has spectral type C7Iab.

Its spectrum reads C7Iab — a carbon star, wrapped in so much soot that its light is filtered to a deep ruby red.

How to see it

Look for La Superba in the constellation CVn. At apparent magnitude 5.42, it can be glimpsed with the unaided eye under dark skies.

Like any astronomical target, La Superba 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 La Superba is an anomaly variable star

La Superba scores 94 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 26 points would lift it into a rarer tier.

That score comes from 10 science badges — Variable star, Distant (over 1,000 light-years), Naked-eye visible, Has a proper name, Carbon star (sooty red), Supergiant, Deep red star and Intrinsically luminous (Mv < −2) — 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.
