Trivia

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 894 thousand years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 79.4 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 509 years in a starship at a tenth of light speed.
Distance. 50.9 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1975.

Saying hello

Say hello. A radio message and its reply would take 102 years round-trip.

Standing on it

A year here. A full year lasts just 308 Earth days.

By the numbers

Mass. Roughly 2225× Earth's mass — about 7 Jupiters.
Temperature. A scorching 55°C on average.

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.

Why HD 160691 e is a trash exoplanet

HD 160691 e scores 11 points on Spacedle's rarity scale, which places it in the trash tier. Another 4 points would lift it into a rarer tier.

That score comes from 2 science badges — Confirmed exoplanet 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.
