Trivia
What it actually is
- What it actually is. Not one galaxy but two, locked in a gravitational embrace. Encounters like this shred spiral arms and trigger furious bursts of star formation.
Sense of scale
- Sense of scale. Galaxies pass through each other almost without collisions — the stars are so far apart that they simply miss.
- 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
- Where to look. You'll find it in the constellation Pisces.
- Seen from everywhere. It sits almost on the celestial equator, so it can be seen from essentially anywhere on Earth.
- Best time of year. It stands highest in the middle of the night around September — that's when to go looking.
How we came to know it
- The New General Catalogue. Its NGC number comes from J. L. E. Dreyer's 1888 catalogue, itself built on decades of sky sweeps by William Herschel and his sister Caroline.

Why NGC 7459 is an uncommon galaxy
NGC 7459 scores 31 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 3 points would lift it into a rarer tier.
That score comes from 3 science badges — Galaxy, Interacting galaxy pair and On the zodiac — 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.
