Answer:
MASS
Which is the most massive planet among the terrestrial planets?
~ The correct answer is Earth.
EARTH
~ Earth’s mass is exactly 5.9736 x 1024 kg or 5,973,600,000,000,000,000,000,000 kg. It is the most massive terrestrial planet -- Venus's (sister planet of Earth) only has 81℅ of Earth's mass.
~ Earth also is the densest planet in the solar system -- it is 5.52 grams per cubic centimeter. This is because of its metallic core with very thick rocky mantle.
HOW TO CALCULATE EARTH'S MASS?
Earth's mass is usually calculated using this formula:
t^{2} =\frac{4\pi^{2}.r^{3} }{g(m + m)}t

=
