Does a star or a tall building have a greater gravitational pull?

The gravitational forces between two objects depend on the masses of both of them,
and also on the distance between the two objects. There's no such thing as the
"gravitational pull" of a single object.
If you keep the same 'test object' in both situations, AND measure the gravitational
forces at the same separation distance between them, then the gravitational forces
between your test object and the star will be greater than those between the test
object and a tall building.
But if you allow your experimental conditions and protocol to become sloppy, then you
can certainly find an object that will be attracted toward a tall building with more force
than another object is attracted toward a star at the same distance, and you can
certainly find a distance from the tall building where an object is attracted to it with
more force than the same object toward a star at a different distance.

How does the density of an object effect its gravitational pull on other objects example when a star's density increases its gravitational pull increases on other objects?
Mass, not density, and the closeness of objects, affects an object's gravitational pull. Density is not dependent on an object's size, but mass is. The more massive an object, and/or the closer an object is to another, the greater its gravitational pull.
What is dependent on gravitational pull?
Any two objects with mass will have a gravitational force. The orbit of planets around stars depends on the gravitational pull of the star. The Earth exerts a gravitational pull on its moon but the moon also exerts a pull on the Earth.
Does a black dwarf have a small gravitational pull?
No. A black dwarf is dense and has the mass of an entire star, so the gravitational pull would still be quite strong.
What is a collapsed star with stromg gravitational pull?
Depending on how big the star was, it could be a white dwarf, a neutron star, or a black hole.
What features does a planet have to have to be a planet?
The features the planet(or soon to be) must posses are: -A gravitational pull -A diameter greater then 800km -An orbit around a star These features were determined by the IAU(International Astronomers Union)
How did all the planets be where they are?
Three of them were grabbed by the gravitational pull of the local star. There are planets that are not in our solar system.
What star has such a strong gravitational pull that no electromagnetic radiation can escape?
It is no longer a star but a cosmic body which hsa imploded into a black hole.
What is a star in which light cannot escape because of the immense gravitational pull at its surface called?
It is a black hole - which is not a star.
What would give a planet a greater gravitational pull?
The only theoretical reason that a planet would have a greater gravitational pull is its mass. This is supported by many natural occurrences, the moon has 1/6 amount of gravity of the Earth, and is smaller. The sun has a gigantic gravitational pull (by our standards) and helps keep the planets in orbit (as well as since the Sun first formed into a star). Also, large gas giants like Jupiter, Saturn, Uranus, and Neptune also have large amount of gravity, according to satellite and computer models. Hope this helps, David
What is the size and gravitational pull of a neutron star?
Multiple questions in a single question. See related questions.
Why does a black hole have tremendous gravitational pull even when its mass is the same as that of the parent star?
It has such a great gravitational pull because of the center(called the singularity) has such a high density that if a airplane where to go through it and come back out it would be the same size as a marble and be the same weight. Therefore black holes have a huge gravitational pull.
What determines the temperature in the core of a star?
The star's mass determines the temperature in its core. A stars mass will also determined it size and the amount of gravitational pull it will have.
