Answer 1

heh??????

Answer 2

Its amazing how much information can be found very quickly on any astronomy site - even wikipedia has this kind of data.

Rigel: radius is 70 solar radii

Procyon B: radius is 1.86 solar radii.

Sun's radius: 6.955 x 10^8 meters.

To get the radii of these stars in meters, multiply the sun's radius by these numbers.

Answer 3

Rigel A's radius is about 54 million kilometers. It is a blue supergiant.

Procyon B's radius is about 8600 kilometers. It's a white dwarf.

Zerowant was right about Procyon B's radius but wrong about Rigel's radius. Lindajune was right about Rigel's radius but wrong about Procyon B's radius.

Answer 4

Procyon B is about 8,600 kilometers in radius (or 8,600,000 meters).

Rigel is about 695,500 kilometers in radius (or 695,500,000 meters)
