Trivia
What makes it special
- Heavyweight. Packed denser than solid iron.
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 9 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 796.8 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 5103 years in a starship at a tenth of light speed.
- Distance. 510 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1516.
Saying hello
- Say hello. A radio message and its reply would take 1021 years round-trip.
Standing on it
- A year here. A full year lasts just 125 Earth days.
By the numbers
- Size. About 12.5× the width of Earth.
- Volume. About 1953 Earths could fit inside it.
- Mass. Roughly 2918× Earth's mass — about 9.2 Jupiters.
- Your weight. You'd weigh about 18.7× your Earth weight standing here.
- Density. Denser than solid iron.
- Temperature. Around 720°C — hotter than a self-cleaning oven.
How we found it
- Discovery. Found by Multiple Observatories using the radial velocity method.

How to see it
Like any astronomical target, HIP 63242 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 HIP 63242 b is an uncommon exoplanet
HIP 63242 b scores 27 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 6 points would lift it into a rarer tier.
That score comes from 3 science badges — Confirmed exoplanet, Gas giant and Denser than iron — 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.
