How many times heavier is the earth?

Answer 1

The Earth's inner core weighs about 1.53E+22 kg.

CALCULATIONS:

The inner core is spherical with a diameter of about 1,250 km (780 miles).

-- Its volume (V = 4/3Ï€r3) is about 1 Billion km cubed (1,022,653,858 km3)

-- V = 4/3Ï€(1250/2)3

[Excel formula: =4/3*PI()*(1250/2)^3]

= 1.022x1018 m3

The estimated average density of the inner core is about 15,000 kg/m³.

-- Weight = volume x density

-- 1.022x1018 (m³) * 15,000 (kg) =

= 1.534x1022 kg

[Excel formula: =(4/3*PI()*(1250*1000/2)^3)*15000]

Answer 2

When you say "how many times heavier" you must be comparing the earth to something else, so your question is incomplete and meaningless. Please revise the question and make it clear what you are using for comparison.

Answer 3

The Earth is about 81 times heavier than the Moon.
