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. ≈ 7.2 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 638.2 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 4087 years in a starship at a tenth of light speed.
- Distance. 409 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1617.
Saying hello
- Say hello. A radio message and its reply would take 817 years round-trip.
Standing on it
