Rigel at closer distances
Rigel is a blue supergiant in Orion, far larger and more luminous than Sirius. Its blue-white globe uses original synthetic mottling: an artistic reconstruction, not a measured global surface map or current photospheric pattern. Interferometry constrains the disc and spectral-line regions; it does not supply the visible surface geography shown here. Automatic rotation remains disabled.

What would Rigel look like inside the Solar System?
At 10 AU, Rigel spans 4.2° across your sky — about 8.1 times the width of the full Moon. Light crosses that gap in 83.2 minutes.
The scene renders the light and the size. Nothing about the physical consequences is modelled.
At this distance, Earth would not survive. Enjoy the view.
How big would Rigel look from twenty-five astronomical units?
At 25 AU, Rigel spans 1.7° across your sky — about 3.2 times the width of the full Moon. Light crosses that gap in 3.5 hours.
Rigel spans a blue-white disc with invented surface mottling and a separate authored optical halo.
How big would Rigel look from one hundred astronomical units?
At 100 AU, Rigel spans 25.0′ across your sky — about 0.81 times the width of the full Moon. Light crosses that gap in 13.9 hours.
The disc remains measurable rather than implied.
How big would Rigel look from one thousand astronomical units?
At 0.02 ly, Rigel spans 2.5′ across your sky — a small fraction of the width of the full Moon. Light crosses that gap in 5.8 days.
Rigel is crossing into an unresolved point source.
How big does Rigel actually look from Earth?
At 860 ly, Rigel spans 0.00 arcseconds across your sky — a small fraction of the width of the full Moon. Light crosses that gap in 860 years.
At its true distance Rigel is among the most luminous stars an unaided eye can see.
What Perigee calculates and what it renders
The apparent size is calculated, but the light, colour and environmental treatment are an authored visualization. Perigee does not model heat, radiation, gravity or tides.
