Trivia

Hard to believe

  • True brightness. It pours out about 319.2 thousand 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 11.1 you'll want a small backyard telescope, over in Taurus.
  • 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 November — that's when to go looking.

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.
