Trivia

What makes it special

Frozen world. A deep-frozen world far from its star's warmth.
Heavyweight. Packed denser than solid iron.

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 2 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 173.6 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 1112 years in a starship at a tenth of light speed.
Distance. 111 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1915.

Saying hello

Say hello. A radio message and its reply would take 222 years round-trip.

Standing on it

A year here. A full year lasts about 9.9 Earth years.

By the numbers

Size. About 12.1× the width of Earth.
Volume. About 1772 Earths could fit inside it.
Mass. Roughly 6007× Earth's mass — about 18.9 Jupiters.
Your weight. You'd weigh about 41.0× your Earth weight standing here.
Density. Denser than solid iron.
Temperature. A frigid -157°C — colder than dry ice.

How we found it

Discovery. Found by La Silla Observatory using the radial velocity method.

About HD 106515 A b

HD 106515 A b is a rare exoplanet. It lies about 111.2 light-years from Earth, has an equilibrium temperature near 117 K, spans roughly 12.1 Earth radii and weighs about 6,006.96 Earth masses.

A deep-frozen world far from its star's warmth.

How to see it

Like any astronomical target, HD 106515 A 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 106515 A b is a rare exoplanet

HD 106515 A b scores 44 points on Spacedle's rarity scale, which places it in the rare tier. Another 2 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Gas giant, Frozen world, Eccentric orbit and Denser than iron — 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.
