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.
  • Lenticular. A lenticular galaxy: it has a disc like a spiral but has run out of the gas needed to make new stars, leaving the arms behind.

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 15 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Aries.
  • 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 October — that's when to go looking.

Could we get there?

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

About NGC 900

NGC 900 is an uncommon galaxy. It lies about 454,533,172.1 light-years from Earth, sits in the constellation Ari and shines at apparent magnitude 14.98.

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 900 in the constellation Ari. At apparent magnitude 14.98, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, NGC 900 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 900 is an uncommon galaxy

NGC 900 scores 32 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 2 points would lift it into a rarer tier.

That score comes from 5 science badges — Galaxy, Outside our galaxy entirely, Lenticular galaxy (a disc with no arms), On the zodiac and Faint fuzzy (mag > 13) — 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.
