There is no magic size or mass required for an object in order to have a ‘satellite’. An ‘orbit’ occurs when the gravitational pull from a nearby object exactly matches the forward motion or momentum of the orbiting body. All objects (with mass) have gravity, however small they are.

Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.

In the theory of gravity as laid out by Newton, mass is the reason for gravity. An attractive force exists between any two masses and causes both the motion of planets and the falling of objects near the Earth’s surface. First, anything with energy can produce gravity or be affected by it, without the need for mass.

If we want a simple answer, most guesses are somewhere around 110000 the mass of earth, or 6⋅1020 kg, but that is very approximate and depends on the composition of the object.

density – The amount of matter in a given space. In scientific terms, density is the amount of mass in a unit of volume.

Space Environment The more matter there is, the more something will weigh. Often, the amount of mass something has is related to its size, but not always. But in space, where the pull of gravity is very small, something can have almost no weight. It still has matter in it, though, so it still has mass.

As the volume of the material increases, the mass will also increase. The greater the volume of the object the greater the number of atoms present. This will result in the object having greater mass.

IN your question the mass is doubled, nothing is given about the volume. If a mass and volume is doubled, what happens to the density? It will stay the same because the 2 and 2 would cancel out and we’d get the same density as the orignal value. Hope that was clear!

Volume and mass are two different and independent quantities. So, there will be no effect on the mass as volume increases. Density =mass / volume. Thus, mass will increase as volume increases.

Density and Volume are inversely proportional to each other. Mass and volume are not the same. When volume increases, density decreases.

Mass, volume and density are three of an object’s most basic properties. Mass is how heavy something is, volume tells you how big it is, and density is mass divided by volume.

Students should realize that if an object weighs more than an equal volume of water, it is more dense and will sink, and if it weighs less than an equal volume of water, it is less dense and will float.

Matter is all the “stuff” that exists in the universe. It has both mass and volume. Volume measures the amount of space that a substance or an object takes up.

The strong force and you. The Higgs field gives mass to fundamental particles—the electrons, quarks and other building blocks that cannot be broken into smaller parts. The energy of this interaction between quarks and gluons is what gives protons and neutrons their mass.

Each ball has the same volume. The baseball, however, is made up of more “matter” so has more mass per unit of volume. Density = Mass/Volume also means that the larger the volume of an object compared to its mass, the less dense it is.

Solids have a definite shape, as well as mass and volume, and do not conform to the shape of the container in which they are placed. Solids also have a high density, meaning that the particles are tightly packed together.

There are three states of matter: solid; liquid and gas. They have different properties, which can be explained by looking at the arrangement of their particles.

About 99 percent of your body is made up of atoms of hydrogen, carbon, nitrogen and oxygen. If we lost all the dead space inside our atoms, we would each be able to fit into a particle of lead dust, and the entire human race would fit into the volume of a sugar cube.
