The distance between planets varies as they move in their orbits. The minimum distance from the Earth to Mars is about 0.35 AU. About how many kilometers is that?

15,000,000 km

25,000,000 km

55,000,000 km

70,000,000 km

Verified Answer :

The distance between the earth and mars is given as 0.35 AU.

AU stands for astronomical unit. It is the macroscopic unit of distance which is used for distance measurement between celestial bodies.

One astronomical unit is defined as the mean distance between the sun and earth.The distance between earth and sun is approximately 150 million kilometre. Hence -

                                      \(1 AU=150 *10^6 km\)

As per the question we have to convert the mean distance between earth and mars from AU unit to kilometre.

The mean distance is given as  0.35 AU

                                                \(= 0.35*150 *10^6 km\)

                                                 \(=52.5*10^6 km\)

                                                 \(= 52,500,00 km\)

The calculated value is approximately close to 55,000,00 km.

Hence option C is right.

                                             



The minimum distance from the Earth to Mars in km is about 55,000,000 km. Option 3 is correct.

What is an astronomical unit?

The astronomical unit, abbreviated as AU, is a unit of measurement used in astronomy It is a macroscopic unit of measurement for the distance between heavenly bodies.

The mean distance between the sun and the earth is specified as an astronomical unit.

The conversion of astronomical unit and km is found as;

\(\rm 1\ AU=150 \times 10^6\ km\)

From the given information the astronomical unit is given as 0.35 AU. Which is converted into the km as;

\(\rm 1\ AU=150 \times 10^6\ km \\\\ \rm 0.35\ AU=0.35 \times 150 \times 10^6\ km \\ \\ d=\ 52,500,00\ km\)

The minimum distance from the Earth to Mars in km is approximately about 55,000,000 km.

Hence Option 3 is correct.
