Trivia
Could we get there?
- Verdict. Impossible with our current technology — and the next millennium of it.
Getting there
- Aboard Voyager 1. ≈ 22.7 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 2 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 12.9 thousand years in a starship at a tenth of light speed.
- Distance. 1293 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 733.
Saying hello
- Say hello. A radio message and its reply would take 2586 years round-trip.
Standing on it
- A year here. A full year lasts just 2.3 Earth days.
By the numbers
- Size. About 4.8× the width of Earth.
- Volume. About 110 Earths could fit inside it.
- Mass. About 20.6× the mass of Earth.
- Your weight. You'd weigh about 0.9× your Earth weight standing here.
How we found it
- Discovery. Found by Transiting Exoplanet Survey Satellite (TESS) using the transit method.

How to see it
Like any astronomical target, TIC 249022743 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 TIC 249022743 b is a common exoplanet
TIC 249022743 b scores 23 points on Spacedle's rarity scale, which places it in the common tier. Another 1 point would lift it into a rarer tier.
That score comes from 4 science badges — Confirmed exoplanet, Neptune-like, Found by TESS 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.
