<p>The black hole has greater pull.</p>

<p>If you stand beside a massive object (planet, star, black hole or anything else with mass) you will feel a gravitational pull, and unless you do something about it you will start to accelerate towards the object.</p>

<p>So the gravitational pull (or more precisely the gravitational acceleration) depends on <em>two</em> things: How massive the object is, and <em>how far you are from its centre</em>. </p>

<p>Neutron stars are all between about 1.2 and 3 times the mass of the sun, any larger and they become black holes. Objects that are believed to be black holes are know with masses of about 4 times the mass of the sun. A black hole can be of any mass, there is no known way for smaller black holes to form.</p>

<p>Now if you fix the distance (say 150 million km), then the gravitational pull depends only on the mass of the object. A neutron star can be at most about three times the mass of the sun, black holes are nearly all larger than that, so the gravitational pull of the black-hole is greater. But if you find a way to make a small black hole, then it would have lower mass and so less gravitational pull, at the same distance.</p>

<p>You can also look at surface gravity. Black holes don't have a proper surface, but you could use the event horizon instead. Here the answer is easy: The gravitational pull becomes infinite at the event horizon (from a certain point of view), Neutron stars have very strong, but not an infinitely strong pull so the gravitational pull of a black hole is greater than a neutron star.</p>

<p>Neutron stars are much more dense. You can get a lot closer to their center before you hit the surface. So at the same mass, a neutron star lets you get closer so as to generate a greater pull.</p>

<p>Neutron Stars and Black Holes are the most dense things in the entire universe. Neutron stars come about when a star collapses and has a supernova. As this happens, the core is smashed with all of the weight of the star put into a single point. Because of the immense pressure, the protons in the core turn into neutrons. This in turn creates a super dense and super heavy dead core of the star it once was. Now even though neutron stars have some of the most immense densities in the entire universe, black holes have them beat. Black holes come when extremely large stars compress their cores so tightly the density of the point hits infinity which creates a black hole. </p>

A neutron star cannot weigh thousands of times that of our sun.   They peak at a bit over 3 solar masses after which they are thought to become black holes.

The gravitational pull is dependent on the mass of the object.  Black holes are usually more massive, but if you found a neutron star and a black hole with the same mass, they would have the same pull.

The black hole has greater pull.

If you stand beside a massive object (planet, star, black hole or anything else with mass) you will feel a gravitational pull, and unless you do something about it you will start to accelerate towards the object.

So the gravitational pull (or more precisely the gravitational acceleration) depends on *two* things: How massive the object is, and *how far you are from its centre*.

Neutron stars are all between about 1.2 and 3 times the mass of the sun, any larger and they become black holes. Objects that are believed to be black holes are know with masses of about 4 times the mass of the sun. A black hole can be of any mass, there is no known way for smaller black holes to form.

Now if you fix the distance (say 150 million km), then the gravitational pull depends only on the mass of the object. A neutron star can be at most about three times the mass of the sun, black holes are nearly all larger than that, so the gravitational pull of the black-hole is greater. But if you find a way to make a small black hole, then it would have lower mass and so less gravitational pull, at the same distance.

You can also look at surface gravity. Black holes don't have a proper surface, but you could use the event horizon instead. Here the answer is easy: The gravitational pull becomes infinite at the event horizon (from a certain point of view), Neutron stars have very strong, but not an infinitely strong pull so the gravitational pull of a black hole is greater than a neutron star.
