Solution

In standard form of a number we put decimal after first digit and remaining power is written as power of 10
So,
Using law of exponents am×an=am+n
Sun =199×1028=1.99×1028×102=1.99×1030

Mercury =33×1022=3.3×1022×10=3.3×1023

Venus =487×1022=4.87×1022×102=4.87×1024

Earth =597×1022=5.97×1022×102=5.97×1024

Mars =642×1027=6.42×1027×102=6.42×1029

Jupiter =19×1026=1.9×1026×10=1.9×1027

Saturn =568×1024=5.68×1024×102=5.68×1026

Uranus =868×1023=8.68×1023×102=8.68×1025

Neptune =102×1024=1.02×1024×102=1.02×1026

Pluto =127×1024=1.27×1020×102=1.27×1022

Moon =795×1020=7.95×1020×102=7.95×1022

So, by comparing masses in standard form,
we get, order of mass of Venus and Earth are same i.e 1024.
So, it has very similar mass as earth
