- Fastest probe ever. ≈ 3.2 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 20.4 thousand years in a starship at a tenth of light speed.
- Distance. 2038 light-years from Earth.
Look-back time
- Look-back time. Its light left before the last ice age ended.
Saying hello
- Say hello. A radio message and its reply would take 4077 years round-trip.
