Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 10.7 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 950.7 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 6089 years in a starship at a tenth of light speed.
- Distance. 609 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1417.
Saying hello
- Say hello. A radio message and its reply would take 1218 years round-trip.
Standing on it
- A year here. A full year lasts just 0.2 Earth days.
By the numbers
- Size. About 13.8× the width of Earth.
- Volume. About 2621 Earths could fit inside it.
- Mass. Roughly 7024× Earth's mass — about 22.1 Jupiters.
- Your weight. You'd weigh about 37.0× your Earth weight standing here.
How we found it
- Discovery. Found by Zwicky Transient Facility using the transit method.

Why ZTF J1230-2655 b is a common exoplanet
ZTF J1230-2655 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 3 science badges — Confirmed exoplanet, Gas giant and Ultra-short period — 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.
