Trivia

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 9.4 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 832 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 5328 years in a starship at a tenth of light speed.
Distance. 533 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1493.

Saying hello

Say hello. A radio message and its reply would take 1066 years round-trip.

Standing on it

A year here. A full year lasts just 3.1 Earth days.

By the numbers

Size. About 12.3× the width of Earth.
Volume. About 1874 Earths could fit inside it.
Mass. Roughly 270× Earth's mass — about 0.9 Jupiters.
Your weight. You'd weigh about 1.8× your Earth weight standing here.
Density. Less dense than water — drop it in a big enough ocean and it would float.
Temperature. Around 971°C — hotter than a self-cleaning oven.

How we found it

Discovery. Found by SuperWASP using the transit method.

Cosmic context

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

About WASP-41 b

WASP-41 b is an uncommon exoplanet. It lies about 532.8 light-years from Earth, has an equilibrium temperature near 1,244 K, spans roughly 12.33 Earth radii and weighs about 270.16 Earth masses.

One of at least 2 planets orbiting its star.

How to see it

Like any astronomical target, WASP-41 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 WASP-41 b is an uncommon exoplanet

WASP-41 b scores 25 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 8 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter 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.
