Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 5.2 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 465 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 2978 years in a starship at a tenth of light speed.
  • Distance. 298 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1728.

Saying hello

  • Say hello. A radio message and its reply would take 596 years round-trip.

Standing on it

  • A year here. A full year lasts just 1.8 Earth days.

By the numbers

  • Size. About 10.1× the width of Earth.
  • Volume. About 1027 Earths could fit inside it.
  • Mass. Roughly 283× Earth's mass — about 0.9 Jupiters.
  • Your weight. You'd weigh about 2.8× your Earth weight standing here.
  • Temperature. Around 927°C — hotter than a self-cleaning oven.

How we found it

  • Discovery. Found by SuperWASP-South using the transit method.

About WASP-145 A b

WASP-145 A b is a common exoplanet. It lies about 297.8 light-years from Earth, has an equilibrium temperature near 1,200 K, spans roughly 10.09 Earth radii and weighs about 282.87 Earth masses.

About 10.1× the width of Earth.

How to see it

Like any astronomical target, WASP-145 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 WASP-145 A b is a common exoplanet

WASP-145 A b scores 19 points on Spacedle's rarity scale, which places it in the common tier. Another 5 points would lift it into a rarer tier.

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