Trivia

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 8.3 it is just past naked-eye reach — ordinary binoculars will pull it in.
  • 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 December — 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. ≈ 9.1 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 812.5 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 5203 years in a starship at a tenth of light speed.

About MWC 758 c

MWC 758 c is an uncommon exoplanet. It lies about 520.3 light-years from Earth, shines at apparent magnitude 8.27, has spectral type A8Ve and has an equilibrium temperature near 500 K.

A scorching 227°C on average.

How to see it

At apparent magnitude 8.27, it is an easy target for binoculars.

Like any astronomical target, MWC 758 c 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 MWC 758 c is an uncommon exoplanet

MWC 758 c scores 33 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 1 point would lift it into a rarer tier.

That score comes from 3 science badges — Confirmed exoplanet, Directly imaged and Orbits beyond Neptune's distance — 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.
