What is the distance between Jupiter and Mars?

Hint: No planet has a circular orbit around the sun, they have usually elliptical orbits or are close to circular orbits. So from this point, we can predict that the distance between Jupiter and Mars should be approximate or have a limit between two numbers like it has some maximum and minimum distance.

Compete answer:

From the above figure, you got an idea about how the planets move in an orbit and how their distance could change with time; this figure represents the case when Mars and Jupiter have minimum distance. The speed of mars is higher than Jupiter so mars completed its orbit before Jupiter and there will be times when mars are on the other end of the orbit and Jupiter would be to the opposite end given in the figure below

In this figure the distance between Jupiter and Mars is maximum. Theoretically, the approximate distance between Jupiter and Mars is or the average distance between Mars and Jupiter in the astronomical unit is \[3.68AU\] .

Note:
The astronomical unit is the unit of length usually used to measure the distance between celestial bodies and it is also used as a scale to measure the distance between celestial bodies. Astronomical unit in kilometer $1AU = 1.46 \times {10^8}km$
There are different methods to find the distance between planets and stars. Some popular method to find is stellar parallax and trigonometric parallax.
Different planets have different speeds where mercury moves fastest with the speed of almost $47.87km/s$ with a period of $87.97$ earth days. Where the slowest moving planet is Venus. The speed of the earth is \[30{\text{ }}km/s\] and it takes the earth \[365{\text{ }}days\] to complete one revolution around the sun.
