Assuming that there is an unlevered firm and a levered firm. The basic information is given by the following table. Table1: Information of the firms Unlevered firm Levered….

## Calculate the average distance of Mercury, Venus and Earth to Mars. Which one of these planets is the closest to Mars on average?

The table below lists the average distance R to the Sun and orbital period T of the first planets: Distance Orbital Period

Mercury 0.39 AU 88 days

Venus 0.72 AU 225 days

Earth 1.00 AU 365 days

Mars 1.52 AU 687 days

(a) Calculate the average distance of Mercury, Venus and Mars to the Earth.

Which one of these planets is the closest to Earth on average?

(b) Calculate the average distance of Mercury, Venus and Earth to Mars.

Which one of these planets is the closest to Mars on average?

(c) What do you expect for the other planets?

Hint: Assume circular orbits and use symmetries to make the distance calculation easier. You can

approximate the average distance by using four well-chosen points on the planet’s orbit.
