Wind power: 100 000 000 x Solar wind | Inclination (major axis): tilted by 57deg from our line-of-sight towards the plane of the sky |
Born masses: 110 + 40? x Sun (2 stars) | Size (major axis): 500 x Solar System |
Present masses: ~70 + 30? x Sun | Total mass (gas+dust): 2 x Sun |
Distance: 7 500 light-years | Mass in dust grains: 1000 x Solar System's planets |
Age: 2.56 Myr (Sun ~ 5 Gyr) | Density (gas): >10 000 particles/cm3 |
Total lifetime: ~3 Myr (Sun ~12 Gyr) | Age - Bipolar flow = 157 years |
