Trivia

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 14.1 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 1.3 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 8035 years in a starship at a tenth of light speed.
Distance. 803 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1223.

Saying hello

Say hello. A radio message and its reply would take 1607 years round-trip.

Standing on it

A year here. A full year lasts just 8.8 Earth days.

By the numbers

Size. About 8.5× the width of Earth.
Volume. About 609 Earths could fit inside it.
Mass. Roughly 91.2× Earth's mass — about 0.3 Jupiters.
Your weight. You'd weigh about 1.3× your Earth weight standing here.
Density. Less dense than water — drop it in a big enough ocean and it would float.
Temperature. Around 667°C — hotter than a self-cleaning oven.

How we found it

Discovery. Found by SuperWASP-North using the transit method.

Cosmic context

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

About WASP-148 b

WASP-148 b is a common exoplanet. It lies about 803.5 light-years from Earth, has an equilibrium temperature near 940 K, spans roughly 8.47 Earth radii and weighs about 91.22 Earth masses.

One of at least 2 planets orbiting its star.

How to see it

Like any astronomical target, WASP-148 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-148 b is a common exoplanet

WASP-148 b scores 15 points on Spacedle's rarity scale, which places it in the common tier. Another 9 points would lift it into a rarer tier.

That score comes from 3 science badges — Confirmed exoplanet, Gas giant 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.
