Trivia

What it actually is

  • What it actually is. A galaxy: a gravitationally bound city of stars, gas and dark matter, turning so slowly that a single rotation takes hundreds of millions of years.
  • Elliptical. An elliptical galaxy: a smooth swarm of stars on randomly tilted orbits, with almost no cold gas left to build anything new.

Sense of scale

  • In perspective. Deep in the extragalactic distance — further than the entire Virgo Cluster of galaxies.
  • Scale. Home to hundreds of billions of stars — a universe unto itself, and every one of those points of light could have planets.

Find it in the sky

  • How to spot it. At magnitude 11.4 you'll want a small backyard telescope, over in Antlia.
  • 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 February — that's when to go looking.

Could we get there?

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

About NGC 3258

NGC 3258 is an uncommon galaxy. It lies about 130,702,731.8 light-years from Earth, sits in the constellation Ant and shines at apparent magnitude 11.41.

A galaxy: a gravitationally bound city of stars, gas and dark matter, turning so slowly that a single rotation takes hundreds of millions of years.

How to see it

Look for NGC 3258 in the constellation Ant. At apparent magnitude 11.41, a small backyard telescope will bring it into view.

Like any astronomical target, NGC 3258 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 NGC 3258 is an uncommon galaxy

NGC 3258 scores 24 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 10 points would lift it into a rarer tier.

That score comes from 3 science badges — Galaxy, Outside our galaxy entirely and Elliptical galaxy — 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.
