Lagrange points are areas in outer space characterized by gravity along the circular motions in outer space. This phenomenon was theorized by a mathematician from France, Louis Lagrange while studying gravity, most specifically the Three body problem. He aimed to investigate why a third small body would rotate a certain body (Earth), which is also […]
Libration refers to the movement of orbiting bodies in relation to one another. For instance, the movement of the Moon Relative to the Earth is an example of a Libration. One of the common examples of Libration is Lunar libration. The moon consists of a singular hemisphere, which faces the earth. Over time more of
A TNO or Trans Neptunian object is any minor planet orbiting the sun in our solar system beyond Neptune, or at a distance which is more than Neptune’s (on average). Known divisions of bodies beyond Neptune which are still part of the solar system are the Kuiper belt, the scattered disk and the Oort cloud.

General relativity is what Albert Einstein theorized in 1916, which describes that gravitation also affects the shape of space and flow of time. It proposed that the bigger the matter, the more it causes the space to curve.

Anything we throw up in the air will fall back to the ground. This is because of the downward pull of gravity, which is causes the downward acceleration of 9.81 meters per second squared. For an object to leave the surface of the earth, without falling back due to gravity, it must possess a speed
In astronomy, physics is an independent field, but it keeps its close relations to the field of space. One term that is widely used in astronomy and also is related to physics is none other than the term called spacetime. The term spacetime is defined as the model where time and space combines as one
People are very conscious of their weight. When they see that they exceed the normal weight they should have, they worry and go on a diet and perform regular exercise. But if they go to the moon or where there is no gravity pulling them down, they become weightless. The earth has a gravitational force
Planets have two motions in space. The first one is their rotation, where they spin on their axis. They also move around the sun, which is called their revolution. On their journey around the sun, they follow an imaginary track called the orbit.
Event horizon, in its simplest definition, is a black hole?s surface. It has a radius of influence that can affect the perception of objects in space. Many astronomy books define it as a very dense region. A teaspoon-full of this object will weigh thousands of tons. Therefore, it has an extreme gravitational pull that even
Many stars are moving together with other stars in space. These groups are called multiple star systems. An example of this system is an eclipsing binary star. It is a pair of stars that revolves on an imaginary ?center.? Their center of revolution is based on their common geometrical center of masses.
