Trivia

Hard to believe

  • True brightness. It pours out about 1.4 million times as much light as the Sun. It only looks ordinary because it is so far away.

Find it in the sky

  • How to spot it. At magnitude 9.5 you'll want a small backyard telescope, over in Sagittarius.
  • 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.

Its true colour

  • Its true colour. Measured through blue and visual filters it comes out deep orange-red (B−V 2.1) — one of the coolest surfaces a star can have while still fusing.

By the numbers

  • Surface temperature. Its colour puts the surface at roughly 3070 K, against the Sun's 5778 K.

What's in a name

  • Its catalogue. The HIP number comes from Hipparcos, the ESA satellite that between 1989 and 1993 pinned down 118,000 stars precisely enough to triangulate their distances.

How to see it

Look for HIP 87956 in the constellation Sgr. At apparent magnitude 9.5, a small backyard telescope will bring it into view.

Like any astronomical target, HIP 87956 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 87956 is an uncommon star

HIP 87956 scores 22 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 12 points would lift it into a rarer tier.

That score comes from 4 science badges — Star, Toward the galactic centre, On the zodiac and Deep red 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.
