What is the weight of a penny on a neutron star?

Answer 1

Two cubic meters of neutron star would have a mass of about 10^18 (1 quintillion) kilograms or about 1 quadrillion metric tons.

Answer 2

If you weighed 100 lb on Earth you would weigh the equivalent of 14,000,000,000,000 lbs on a Neutron Star.

• 1lb = 140,000,000,000
• 5lb = 700,000,000,000
• 10lb = 1,400,000,000,000
• 25lb = 3,500,000,000,000
• 50lb = 7,000,000,000,000
• 100lb = 14,000,000,000,000
• 150lb = 21,000,000,000,000
• 200lb = 28,000,000,000,000
• 500lb = 70,000,000,000,000

Or multiply x 140,000,000,000

Answer 3

It would have no weight as the massive gravity would have stripped the penny apart, atom by atom. So it would no longer be a penny.

Also - there are many kinds of penny all with different weights.

If it was possible - and it's not - the weight of the penny would be about 140,000,000,000 times that on Earth.

Answer 4

A typical neutron star will have surface gravity about 1 trillion times that of Earth. So a 100 lb person would weigh 100 trillion lbs or about 50 billion tons. Such a weight is comparable to what a mountain weighs on Earth.
