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.
  • Irregular. An irregular galaxy — no disc, no bulge, no symmetry. Most have been pulled out of shape by a larger neighbour's gravity.

Sense of scale

  • 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 10.7 you'll want a small backyard telescope, over in Indus.
  • 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 August — that's when to go looking.

Its true colour

  • Its true colour. Its colour is a census: blue where gas is still collapsing into hot young stars, yellow-red in the old, settled core.

How we came to know it

  • The Index Catalogue. The IC was the 1895 and 1908 supplement to the NGC — the first catalogue in history to be filled largely with objects found on photographic plates rather than by eye.

About IC 5152

IC 5152 is an uncommon galaxy. It sits in the constellation Ind and shines at apparent magnitude 10.68.

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 IC 5152 in the constellation Ind. At apparent magnitude 10.68, a small backyard telescope will bring it into view.

Like any astronomical target, IC 5152 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 IC 5152 is an uncommon galaxy

IC 5152 scores 26 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 8 points would lift it into a rarer tier.

That score comes from 2 science badges — Galaxy and Irregular galaxy (no shape at all) — 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.
