Trivia

Hard to believe

True brightness. It pours out about 691.8 thousand times as much light as the Sun. It only looks ordinary because it is so far away.

What it actually is

Spectral class. Its spectrum reads R... — a carbon star, wrapped in so much soot that its light is filtered to a deep ruby red.

Find it in the sky

How to spot it. At magnitude 10.2 you'll want a small backyard telescope, over in Cancer.
Seen from everywhere. It sits almost on the celestial equator, so it can be seen from essentially anywhere on Earth.
Best time of year. It stands highest in the middle of the night around January — that's when to go looking.

Its true colour

Its true colour. Measured through blue and visual filters it comes out orange (B−V 1.3) — cooler than the Sun, and the kind of star that burns steadily for tens of billions of years.

By the numbers

Surface temperature. Its colour puts the surface at roughly 4200 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.

Why HIP 42672 is a trash star

HIP 42672 scores 6 points on Spacedle's rarity scale, which places it in the trash tier. Another 9 points would lift it into a rarer tier.

That score comes from 2 science badges — Star and On the zodiac — 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.
