Trivia

Could we get there?

  • Verdict. Impossible with our current technology — and the next millennium of it.

Getting there

  • Aboard Voyager 1. ≈ 29.9 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 2.7 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 17 thousand years in a starship at a tenth of light speed.
  • Distance. 1700 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 326.

Saying hello

  • Say hello. A radio message and its reply would take 3400 years round-trip.

Standing on it

  • A year here. A full year lasts just 2.8 Earth days.

By the numbers

  • Size. About 11.5× the width of Earth.
  • Volume. About 1508 Earths could fit inside it.
  • Mass. Roughly 203× Earth's mass — about 0.6 Jupiters.
  • Your weight. You'd weigh about 1.5× your Earth weight standing here.
  • Density. Less dense than water — drop it in a big enough ocean and it would float.
  • Temperature. Around 828°C — hotter than a self-cleaning oven.

How we found it

  • Discovery. Found by Next-Generation Transit Survey (NGTS) using the transit method.

About NGTS-25 b

NGTS-25 b is an uncommon exoplanet. It lies about 1,700 light-years from Earth, has an equilibrium temperature near 1,101 K, spans roughly 11.47 Earth radii and weighs about 203.09 Earth masses.

About 11.5× the width of Earth.

How to see it

Like any astronomical target, NGTS-25 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 NGTS-25 b is an uncommon exoplanet

NGTS-25 b scores 29 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 4 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter and Distant (>1000 ly) — 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.
