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.
  • Spiral. A spiral galaxy. Those arms are not solid structures but traffic jams — density waves that stars drift into and out of as they orbit.

Sense of scale

  • In perspective. Further than Andromeda, the most distant thing the unaided human eye can see.
  • 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 13 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Canes Venatici.
  • 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 April — that's when to go looking.

Could we get there?

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

About NGC 4707

NGC 4707 is an uncommon galaxy. It lies about 21,804,741.3 light-years from Earth, sits in the constellation CVn and shines at apparent magnitude 12.97.

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 4707 in the constellation CVn. At apparent magnitude 12.97, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, NGC 4707 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 4707 is an uncommon galaxy

NGC 4707 scores 25 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 9 points would lift it into a rarer tier.

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