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 10.6 you'll want a small backyard telescope, over in Ara.
  • Southern sky only. So far south it never rises for most of the northern hemisphere. To see it you'd have to travel to Chile, South Africa or Australia.
  • Best time of year. It stands highest in the middle of the night around June — that's when to go looking.

Could we get there?

  • Verdict. Hopelessly far for any craft humanity can build today.

Getting there

  • Aboard Voyager 1. ≈ 9.3 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 829.4 thousand years even at the Parker Solar Probe's 192 km/s.

About HIP 83003

HIP 83003 is an uncommon variable star. It lies about 531.2 light-years from Earth, sits in the constellation Ara and shines at apparent magnitude 10.62.

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 83003 in the constellation Ara. At apparent magnitude 10.62, a small backyard telescope will bring it into view.

Like any astronomical target, HIP 83003 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 83003 is an uncommon variable star

HIP 83003 scores 23 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 11 points would lift it into a rarer tier.

That score comes from 4 science badges — Variable star, Blue-white star, Strongly 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.
