Stellar stream round Andromeda
Eastern Shelf
A shell of debris, probably from the same accretion as the Giant Stream (Fardal et al. models, as McConnachie et al. 2018 summarise).
Measured
- Distance
- about 2.5 million light-years
How far, from the Sun
About 2.5 million light-years. To cross it:
- Light2.5 million years
- Voyager 1's speed44.4 billion years
- Driving at 100 km/h27 trillion years
Voyager 1 at the speed it moved outward over the year to 2026-10-25 (JPL Horizons). Driving: nonstop, never refuelling.
