Trivia

What makes it special

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

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 7.7 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 687 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 4400 years in a starship at a tenth of light speed.
Distance. 440 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1586.

Saying hello

Say hello. A radio message and its reply would take 880 years round-trip.

By the numbers

Size. About 17.9× the width of Earth.
Volume. About 5768 Earths could fit inside it.
Mass. Roughly 1541× Earth's mass — about 4.9 Jupiters.
Your weight. You'd weigh about 4.8× your Earth weight standing here.
Temperature. A frigid -240°C — colder than dry ice.

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 WISPIT 2 b

WISPIT 2 b is a rare exoplanet. It lies about 440 light-years from Earth, has an equilibrium temperature near 33 K, spans roughly 17.93 Earth radii and weighs about 1,541.47 Earth masses.

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

How to see it

Like any astronomical target, WISPIT 2 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 WISPIT 2 b is a rare exoplanet

WISPIT 2 b scores 39 points on Spacedle's rarity scale, which places it in the rare tier. Another 7 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Gas giant, Frozen 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.
