Suppose we wanted to represent all of these objects on the 1-to-10-billion scale from chapter 1, on which the sun is about the size of a grapefruit. approximately how large in diameter would the star aldebaran be on this scale?

6.62 m

About 44.14 grapefruits lined in a single line would be the length of the diameter of star Aldebaran

Explanation:

First we know,

Diameter of the Sun - 1.39 million km (Ds)

Diameter of Aldbaran - 61.40 million km (Da)

Thus,

=   ≈ 44.14

We know that in this scale the size of the sun is that of a grapefruit.

The average diameter of a grapefruit is about 15cm

Thus  Ds in this scale is 15cm

Thus Da in this scale,

Da = Ds *44.14

Da = 0.15 * 44.14 ≈ 6.62 m

Thus the diameter of Aldebaran in this scale is 6.62 m

Explanation:

Cuando la pelota se va por sobre la línea de costado (o sobre la línea de fondo tocada por un jugador de campo del equipo defensor) se ejecuta un saque lateral.
