Trivia

What makes it special

Packed system. Crammed into a system of five or more planets.

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 1.5 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 136.4 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 874 years in a starship at a tenth of light speed.
Distance. 87.4 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1939.

Saying hello

Say hello. A radio message and its reply would take 175 years round-trip.

Standing on it

A year here. A full year lasts just 12.1 Earth days.

By the numbers

Size. About 3× the width of Earth.
Volume. About 26.2 Earths could fit inside it.
Mass. About 9.1× the mass of Earth.
Your weight. You'd weigh about 1.0× your Earth weight standing here.
Temperature. Around 621°C — hotter than a self-cleaning oven.

How we found it

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

Cosmic context

Crowded system. One of at least 5 planets orbiting its star.

Crammed into a system of five or more planets.

How to see it

Like any astronomical target, HD 134606 b 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 HD 134606 b is an uncommon exoplanet

HD 134606 b scores 30 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 3 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Sub-Neptune, Multi-planet system and Richly packed 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.
