In everyday life
- Light from this object takes about 5,000 years to reach Earth — the light you see tonight left 5,000 years ago (official distance ÷ speed of light).
- At magnitude 6.3 it is fainter than the naked-eye limit (about 6) — you need binoculars or a telescope.
- It spans about 29′ of sky — about the same as the full Moon's 31′.
