Trivia

What it actually is

  • Spectral class. Its spectrum reads F8 — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
  • 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 10.4 you'll want a small backyard telescope, over in Canes Venatici.
  • Northern sky. It rides the northern half of the sky — an easier target the further north you are.
  • Best time of year. It stands highest in the middle of the night around April — 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. ≈ 13.7 million years at Voyager 1's speed (17 km/s).

About HIP 63701

HIP 63701 is a common variable star. It lies about 782.1 light-years from Earth, sits in the constellation CVn, shines at apparent magnitude 10.45 and has spectral type F8.

Its spectrum reads F8 — an F-type star — a little hotter, whiter and shorter-lived than the Sun.

How to see it

Look for HIP 63701 in the constellation CVn. At apparent magnitude 10.45, a small backyard telescope will bring it into view.

Like any astronomical target, HIP 63701 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 63701 is a common variable star

HIP 63701 scores 15 points on Spacedle's rarity scale, which places it in the common tier. Another 7 points would lift it into a rarer tier.

That score comes from 4 science badges — Variable star, Yellow-white F-type star, Gently 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.
