Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 1.2 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 102.8 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 659 years in a starship at a tenth of light speed.
  • Distance. 65.9 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1960.

Saying hello

  • Say hello. A radio message and its reply would take 132 years round-trip.

Standing on it

  • A year here. A full year lasts just 123 Earth days.

By the numbers

  • Size. About 4.9× the width of Earth.
  • Volume. About 116 Earths could fit inside it.
  • Mass. About 21.1× the mass of Earth.
  • Your weight. You'd weigh about 0.9× your Earth weight standing here.
  • Temperature. A frigid -97°C — colder than dry ice.

How we found it

  • Discovery. Found by La Silla Observatory using the radial velocity method.

Cosmic context

  • Crowded system. One of at least 4 planets orbiting its star.

About GJ 3293 c

GJ 3293 c is a common exoplanet. It lies about 65.9 light-years from Earth, has an equilibrium temperature near 177 K, spans roughly 4.87 Earth radii and weighs about 21.09 Earth masses.

One of at least 4 planets orbiting its star.

How to see it

Like any astronomical target, GJ 3293 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 GJ 3293 c is a common exoplanet

GJ 3293 c scores 15 points on Spacedle's rarity scale, which places it in the common tier. Another 9 points would lift it into a rarer tier.

That score comes from 3 science badges — Confirmed exoplanet, Neptune-like and Multi-planet system — 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.
