Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 10.2 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 906.2 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 5804 years in a starship at a tenth of light speed.
  • Distance. 580 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1446.

Saying hello

  • Say hello. A radio message and its reply would take 1161 years round-trip.

Standing on it

  • A year here. A full year lasts just 34.5 Earth days.

By the numbers

  • Size. About 10.1× the width of Earth.
  • Volume. About 1030 Earths could fit inside it.
  • Mass. Roughly 178× Earth's mass — about 0.6 Jupiters.
  • Your weight. You'd weigh about 1.7× your Earth weight standing here.
  • Density. Less dense than water — drop it in a big enough ocean and it would float.
  • Temperature. A scorching 224°C on average.

How we found it

  • Discovery. Found by Transiting Exoplanet Survey Satellite (TESS) using the transit method.

Cosmic context

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

About TOI-216.01

TOI-216.01 is a common exoplanet. It lies about 580.4 light-years from Earth, has an equilibrium temperature near 497 K, spans roughly 10.1 Earth radii and weighs about 177.98 Earth masses.

One of at least 2 planets orbiting its star.

How to see it

Like any astronomical target, TOI-216.01 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 TOI-216.01 is a common exoplanet

TOI-216.01 scores 19 points on Spacedle's rarity scale, which places it in the common tier. Another 5 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Multi-planet system and Found by TESS — 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.
