Getting there
- Aboard Voyager 1. ≈ 25.9 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 2.3 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 14.7 thousand years in a starship at a tenth of light speed.
- Distance. 1474 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 552.
Saying hello
- Say hello. A radio message and its reply would take 2947 years round-trip.

By the numbers
- Size. About 2× the width of Earth.
- Volume. About 7.9 Earths could fit inside it.
- Mass. About 4.6× the mass of Earth.
