Question - Determining Closest Planets by Distance
Solution:
According to the table provided, we need to compare the distances between different pairs of planets to determine which pair is closest to each other. To do this, we look at the 'Distance (km)' column and find the smallest number.Here are the distances provided for each pair of planets in scientific notation:- Mercury to Saturn: 1.37 x 10^9 km- Venus to Jupiter: 6.72 x 10^8 km- Earth to Neptune: 4.35 x 10^9 km- Saturn to Jupiter: 3.46 x 10^8 km- Earth to Mars: 7.83 x 10^7 kmWhen comparing numbers in scientific notation, you can compare the exponents first. The smallest exponent here is 7 (in 7.83 x 10^7), which corresponds to the Earth to Mars distance. The smaller the exponent, the smaller the number.Therefore, the smallest distance among the given options is the one between Earth and Mars, which is 7.83 x 10^7 km. This means the correct answer is Earth and Mars.
