Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 1.3 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 114.3 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 732 years in a starship at a tenth of light speed.
  • Distance. 73.2 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1953.

Saying hello

  • Say hello. A radio message and its reply would take 146 years round-trip.

Standing on it

  • A year here. A full year lasts just 5.1 Earth days.

By the numbers

  • Size. About 1.1× the width of Earth.
  • Mass. About 1.5× the mass of Earth.
  • Your weight. You'd weigh about 1.2× your Earth weight standing here.
  • Temperature. A scorching 260°C on average.

How we found it

  • Discovery. Found by Gemini Observatory using the transit method.

Cosmic context

  • Crowded system. One of at least 2 planets orbiting its star.

Why TOI-1450 A c is an uncommon exoplanet

TOI-1450 A c scores 27 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 6 points would lift it into a rarer tier.

That score comes from 3 science badges — Confirmed exoplanet, Earth-sized 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.
