Question

Mercury, Venus, and Earth are the three planets closest to the Sun. Would their combined distance from the Sun be greater or less than the distance from the sun to Neptune? Show your work and justify your answer.


Answer 1

The distance from Mercury to Sun is  57,9 * 10⁶km.
The distance from Venus to Sun is  108,2 *10⁶km.
The distance from Earth to Sun is  149,6 *10⁶km.

57,9 *10⁶+ 108,2 *10⁶+ 149,6 *10⁶ ≈ 315,7 *10⁶km 

The distance from Neptune to Sun is  4503 *10⁶km.

That means their combined distanceis less than
the distance from the Sun to Neptune.
