Trivia

Could we get there?

  • Verdict. Hopelessly far for any craft humanity can build today.

Getting there

  • Aboard Voyager 1. ≈ 8.7 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 769.3 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 4927 years in a starship at a tenth of light speed.
  • Distance. 493 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1533.

Saying hello

  • Say hello. A radio message and its reply would take 985 years round-trip.

How we found it

  • Named. Notable enough to have earned a proper name, not just a catalogue number.

About Mirzam

Mirzam is a trash variable star. It lies about 492.7 light-years from Earth, sits in the constellation CMa, shines at apparent magnitude 1.98 and has spectral type B1II/III.

Notable enough to have earned a proper name, not just a catalogue number.

How to see it

Look for Mirzam in the constellation CMa. At apparent magnitude 1.98, it can be glimpsed with the unaided eye under dark skies.

Like any astronomical target, Mirzam 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 Mirzam is a trash variable star

Mirzam scores 13 points on Spacedle's rarity scale, which places it in the trash tier. Another 2 points would lift it into a rarer tier.

That score comes from 2 science badges — Variable star and Has a proper name — 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.
