If we were to magically replace our sun with the supergiant star, betelgeuse, how many planets in our solar system would be inside of the star itself? (hint: compare the semi-major axis of the planets to the stars radius). clearly state the values that you find and convert to answer this question.

Mercury, Venus, Earth and Mars

Explanation:

The radius of the super giant star Betelgeuse star is about 800 times the radius of the Sun.

Radius of Betelgeuse = 800 × 695510 km  = 5.56×10⁷ km = 3.72 AU

Semi Major axis of Mercury = 0.3 AU

Semi Major axis of Venus = 0.72 AU

Semi Major axis of Earth = 1 AU

Semi Major axis of Mars = 1.5 AU

Semi Major axis of Jupiter = 5.2 AU

Thus, from the above data, it can be concluded that Mercury, Venus, Earth and Mars would be within the star itself.
