Question

describing characteristics of stars
complete the paragraph to describe the characteristics of the sun and rigel, a blue - white supergiant.
rigel and the sun have similar characteristics, but they also differ in some ways. rigel and the sun are spheres of gas that use nuclear fusion to produce energy. rigel is

the sun. rigel has

the sun. rigel has a surface temperature of about

Explanation:

To solve this, we use astronomical knowledge about stars:

1. First blank (size/volume): Rigel is a supergiant, so it’s larger than the Sun.
2. Second blank (mass/luminosity): Supergiants like Rigel have more mass than (or higher luminosity than) the Sun.
3. Third blank (temperature): Blue - white stars (like Rigel) have a surface temperature of about 11,000–30,000 K (or more precisely, around 12,000 K, but typical ranges for blue - white supergiants are in this bracket; the Sun’s surface temp is ~5,778 K).

(Note: If dropdown options were provided, we’d match these: e.g., first dropdown “larger than”, second “more massive than”, third “12,000 K” or similar typical value for blue - white supergiant temp.)

For a filled - in paragraph (assuming common dropdown options):

Rigel and the Sun have similar characteristics, but they also differ in some ways. Rigel and the Sun are spheres of gas that use nuclear fusion to produce energy. Rigel is $\boldsymbol{\text{larger than}}$ the Sun. Rigel has $\boldsymbol{\text{more mass than}}$ the Sun. Rigel has a surface temperature of about $\boldsymbol{\text{12,000 K}}$ (or other appropriate temp from dropdown, e.g., 11,000 K - 30,000 K range option).
