Trivia

Could we get there?

  • Verdict. Hopelessly far for any craft humanity can build today.

Getting there

  • Aboard Voyager 1. ≈ 609.1 thousand years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 54.1 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 347 years in a starship at a tenth of light speed.
  • Distance. 34.7 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1991.

Saying hello

  • Say hello. A radio message and its reply would take 69.3 years round-trip.

Standing on it

  • A year here. A full year lasts just 5.5 Earth days.

By the numbers

  • Size. About 1.1× the width of Earth.
  • Mass. About 1.4× the mass of Earth.
  • Your weight. You'd weigh about 1.1× your Earth weight standing here.
  • Temperature. A scorching 49°C on average.

How we found it

  • Discovery. Found by Calar Alto Observatory using the radial velocity method.

About G 261-6 b

G 261-6 b is a common exoplanet. It lies about 34.7 light-years from Earth, has an equilibrium temperature near 322 K, spans roughly 1.1 Earth radii and weighs about 1.37 Earth masses.

About 1.1× the width of Earth.

How to see it

Like any astronomical target, G 261-6 b 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 G 261-6 b is a common exoplanet

G 261-6 b scores 21 points on Spacedle's rarity scale, which places it in the common tier. Another 3 points would lift it into a rarer tier.

That score comes from 2 science badges — Confirmed exoplanet and Earth-sized — 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.
