Trivia

What it actually is

  • Spectral class. Its spectrum reads A1m... — an A-type star: white-hot, typically about twice the Sun's mass, and the class most of the sky's famous bright stars belong to.

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 7.8 it is just past naked-eye reach — ordinary binoculars will pull it in, over in Piscis Austrinus.
  • 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 September — 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. ≈ 10.1 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 893.4 thousand years even at the Parker Solar Probe's 192 km/s.

Why HD 216290 is a trash star
