Trivia

What it actually is

  • Spectral class. Its spectrum reads F0II — an F-type star — a little hotter, whiter and shorter-lived than the Sun.
  • Where it is in life. It is a bright giant, well on its way to the largest stars there are.

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 5 you can see it with your own eyes from a dark site, over in Camelopardalis.
  • 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 November — that's when to go looking.

Could we get there?

  • Verdict. Impossible with our current technology — and the next millennium of it.

Getting there

  • Aboard Voyager 1. ≈ 35.8 million years at Voyager 1's speed (17 km/s).

About HR 1242

HR 1242 is a rare star. It lies about 2,038.5 light-years from Earth, sits in the constellation Cam, shines at apparent magnitude 5 and has spectral type F0II.

Its spectrum reads F0II — an F-type star — a little hotter, whiter and shorter-lived than the Sun.

How to see it

Look for HR 1242 in the constellation Cam. At apparent magnitude 5, it can be glimpsed with the unaided eye under dark skies.

Like any astronomical target, HR 1242 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 HR 1242 is a rare star

HR 1242 scores 46 points on Spacedle's rarity scale, which places it in the rare tier. Another 4 points would lift it into a rarer tier.

That score comes from 7 science badges — Star, Distant (over 1,000 light-years), Naked-eye visible, Never sets (northern circumpolar), Yellow-white F-type star, Bright giant and Intrinsically luminous (Mv < −2) — 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.
