Which of the following units is likely to be used while calculating the distance between Venus and Earth?

A) Astronomical units
B) Days
C) Kilometers per hour
D) Miles per second

Answer 1

The correct answer is option A, that is, astronomical units.

The astronomical unit refers to a unit of length, roughly the distance from Earth to the Sun. However, that distance changes as Earth orbits the Sun, from an aphelion to a perihelion and back again once a year.

The astronomical unit is utilized mainly for calculating the distances within the Solar system or around other stars.
