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. ≈ 112 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 718 years in a starship at a tenth of light speed.
Distance. 71.8 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1954.

Saying hello

Say hello. A radio message and its reply would take 144 years round-trip.

Standing on it

A year here. A full year lasts just 41.8 Earth days.

By the numbers

Size. About 3.2× the width of Earth.
Volume. About 33.7 Earths could fit inside it.
Mass. About 10.5× the mass of Earth.
Your weight. You'd weigh about 1.0× your Earth weight standing here.
Temperature. A scorching 271°C on average.

How we found it

Discovery. Found by Multiple Observatories using the radial velocity method.

Cosmic context

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

Why HD 164922 e is a common exoplanet

HD 164922 e scores 16 points on Spacedle's rarity scale, which places it in the common tier. Another 8 points would lift it into a rarer tier.

That score comes from 3 science badges — Confirmed exoplanet, Sub-Neptune 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.
