# Question: How Dense Is A Neutron Star Compared To Earth?

## What would happen if you touched a neutron star?

So when anything tries to touch neutron star, it would be suck in by gravity and collapse into lump of neutrons and feed their mass into that neutron star.

And if it collects enough mass it would collapse into a black hole.

Despite pop-science descriptions, neutron stars do not contain only neutrons..

## How big is a neutron star compared to Earth?

Despite their small diameters—about 12.5 miles (20 kilometers)—neutron stars boast nearly 1.5 times the mass of our sun, and are thus incredibly dense. Just a sugar cube of neutron star matter would weigh about one hundred million tons on Earth.

## How many times more dense is a neutron star than the Earth?

The neutron star’s density also gives it very high surface gravity, with typical values ranging from 1012 to 1013 m/s2 (more than 1011 times that of Earth).

## What is the density of a neutron star comparable to?

Neutrons stars are extreme objects that measure between 10 and 20 km across. They have densities of 1017 kg/m3(the Earth has a density of around 5×103 kg/m3 and even white dwarfs have densities over a million times less) meaning that a teaspoon of neutron star material would weigh around a billion tonnes.

## Is a neutron star heavy?

A neutron star has a mass of about 1.4 times the mass of the sun, but is not much bigger than a small city, about 15 km in radius. A teaspoon of neutron star material would weigh about 10 million tons. The gravitational field is intense; the escape velocity is about 0.4 times the speed of light.

## What happens if 2 neutron stars collide?

A neutron star is what’s left when a star burns out and collapses in on itself, leaving a small, incredibly dense ball. Einstein’s theory of general relativity predicted that when two neutron stars collide, they would generate a gravitational wave, a ripple in space time.
