Question

the combined mass of the moon, Earth, and Pluto is 5.986 x 10²⁴ . How many combined moon, Earth, and Pluto masses are needed to equal the mass of the sun (1.898 x 10³⁰)

Answer 1

3.16 x 10⁵ or 316,000

Explanation:

We can start by dividing the mass of the sun by the combined mass of the moon, Earth, and Pluto:

1.898 x 10³⁰ / 5.986 x 10²⁴ ≈ 3.16 x 10⁵

This means that approximately 3.16 x 10⁵ (or 316,000) combined masses of the moon, Earth, and Pluto are needed to equal the mass of the sun.
