Trivia

What it actually is

  • It changes. This star does not hold still: its brightness rises and falls on a rhythm of hours, days or years, either pulsing in size or being eclipsed by a companion.

Sense of scale

  • In perspective. Far away by human standards, yet still a local address inside the Milky Way's spiral arms.

Find it in the sky

  • How to spot it. At magnitude 10.2 you'll want a small backyard telescope, over in Andromeda.
  • 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 September — that's when to go looking.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 22.2 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 2 million years even at the Parker Solar Probe's 192 km/s.

About HIP 116716

HIP 116716 is a common variable star. It lies about 1,264.2 light-years from Earth, sits in the constellation And and shines at apparent magnitude 10.17.

This star does not hold still: its brightness rises and falls on a rhythm of hours, days or years, either pulsing in size or being eclipsed by a companion.

How to see it

Look for HIP 116716 in the constellation And. At apparent magnitude 10.17, a small backyard telescope will bring it into view.

Like any astronomical target, HIP 116716 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 HIP 116716 is a common variable star

HIP 116716 scores 18 points on Spacedle's rarity scale, which places it in the common tier. Another 4 points would lift it into a rarer tier.

That score comes from 4 science badges — Variable star, Distant (over 1,000 light-years), Gently variable and A named variable star — 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.
