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 12.2 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Ara.
  • Southern sky. It rides the southern half of the sky — an easier target the further south you are.
  • 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. ≈ 4.6 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 409.7 thousand years even at the Parker Solar Probe's 192 km/s.

About HIP 88402

HIP 88402 is a common variable star. It lies about 262.4 light-years from Earth, sits in the constellation Ara and shines at apparent magnitude 12.17.

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 88402 in the constellation Ara. At apparent magnitude 12.17, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, HIP 88402 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 88402 is a common variable star

HIP 88402 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 3 science badges — Variable 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.
