Trivia

What makes it special

Lava world. Its surface is likely an ocean of molten rock.

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 6.5 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 575.8 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 3688 years in a starship at a tenth of light speed.
Distance. 369 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1657.

Saying hello

Say hello. A radio message and its reply would take 738 years round-trip.

Standing on it

A year here. A full year lasts about 119 Earth years.

By the numbers

Size. About 22× the width of Earth.
Volume. About 10.6 thousand Earths could fit inside it.
Mass. Roughly 1017× Earth's mass — about 3.2 Jupiters.
Your weight. You'd weigh about 2.1× your Earth weight standing here.
Density. Less dense than water — drop it in a big enough ocean and it would float.
Temperature. Around 1119°C — hotter than a self-cleaning oven.

How we found it

Discovery. Found by Paranal Observatory using the imaging method.

Cosmic context

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

About PDS 70 b

PDS 70 b is an epic exoplanet. It lies about 368.8 light-years from Earth, has an equilibrium temperature near 1,392 K, spans roughly 21.97 Earth radii and weighs about 1,017.05 Earth masses.

Its surface is likely an ocean of molten rock.

How to see it

Like any astronomical target, PDS 70 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 PDS 70 b is an epic exoplanet

PDS 70 b scores 65 points on Spacedle's rarity scale, which places it in the epic tier. Another 3 points would lift it into a rarer tier.

That score comes from 7 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Lava world, Long-period world, Multi-planet system and Directly imaged — 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.
