Trivia
What makes it special
- Frozen world. A deep-frozen world far from its star's warmth.
- 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. ≈ 2.7 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 243.4 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 1559 years in a starship at a tenth of light speed.
- Distance. 156 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1870.
Saying hello
- Say hello. A radio message and its reply would take 312 years round-trip.
Standing on it
- A year here. A full year lasts about 20.1 Earth years.
By the numbers
- Size. About 12.2× the width of Earth.
- Volume. About 1816 Earths could fit inside it.
- Mass. Roughly 4868× Earth's mass — about 15.3 Jupiters.
- Your weight. You'd weigh about 32.7× your Earth weight standing here.
- Density. Denser than solid iron.
- Temperature. A frigid -166°C — colder than dry ice.
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.
