Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 487.4 thousand years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 43.3 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 277 years in a starship at a tenth of light speed.
- Distance. 27.7 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1998.
Saying hello
- Say hello. A radio message and its reply would take 55.5 years round-trip.
Standing on it
- A year here. A full year lasts just 123 Earth days.
By the numbers
- Size. About 5.1× the width of Earth.
- Volume. About 133 Earths could fit inside it.
- Mass. About 22.9× the mass of Earth.
- Your weight. You'd weigh about 0.9× your Earth weight standing here.
- Density. Less dense than water — drop it in a big enough ocean and it would float.
- Temperature. A scorching 109°C on average.
How we found it
- Discovery. Found by Multiple Observatories using the radial velocity method.
Cosmic context
- Crowded system. One of at least 3 planets orbiting its star.

How to see it
Like any astronomical target, 61 Vir d 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 61 Vir d is a common exoplanet
61 Vir d scores 15 points on Spacedle's rarity scale, which places it in the common tier. Another 9 points would lift it into a rarer tier.
That score comes from 3 science badges — Confirmed exoplanet, Neptune-like and Multi-planet system — 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.
